This is due to Lua calling `hlua_alloc()` with `ptr = NULL` and `nsize = 0`.
While `realloc` is supposed to be equivalent `free()` if the size is `0` this
is only required for a non-NULL pointer. Apparently my allocator (or valgrind)
actually allocates a zero size area if the pointer is NULL, possibly taking up
some memory for management structures.
Fix this leak by specifically handling the case where both the pointer and the
size are `0`.
This bug appears to have been introduced with the introduction of the
multi-threaded Lua, thus this fix is specific for 2.4. No backport needed.
It is now possible to set the buffer used by the channel request buffer when
a stream is created. It may be useful if input data are already received,
instead of waiting the first call to the mux rcv_buf() callback. This change
is mandatory to support H1 connection with no stream attached.
For now, the multiplexers don't pass any buffer. BUF_NULL is thus used to
call stream_create_from_cs().
It seems to me that lua_close() must be called on all states at deinit
time, not just the first two ones. This is likely a remnant of commit
59f11be43 ("MEDIUM: lua-thread: Add the lua-load-per-thread directive").
There should likely be some memory leak reports when using Lua without
this fix, though none were observed for now.
No backport is needed as this was merged into 2.4-dev.
Lua dedicated TCP, HTTP and SSL socket and proxies must be initialized
once. Right now, they are initialized from the Lua init state, but since
commit 59f11be43 ("MEDIUM: lua-thread: Add the lua-load-per-thread
directive") this function is called one time per lua context. This
caused some fields to be cleared and overwritten, and pre-allocated
object to be lost. This is why the address sanitizer detected memory
leaks from the socket_ssl server initialization.
Let's move all the state-independent part of the function to the
hlua_init() function to avoid this.
No backport is needed, this is only 2.4-dev.
The goal is to allow execution of one main lua state per thread.
This patch contains the main job. The lua init is done using these
steps:
- "lua-load-per-thread" loads the lua code in the first thread
- it creates the structs
- it stores loaded files
- the 1st step load is completed (execution of hlua_post_init)
and now, we known the number of threads
- we initilize lua states for all remaining threads
- for each one, we load the lua file
- for each one, we execute post-init
Once all is loaded, we control consistency of functions references.
The rules are:
- a function reference cannot be in the shared lua state and in
a per-thread lua state at the same time.
- if a function reference is declared in a per-thread lua state, it
must be declared in all per-thread lua states
The goal is to allow execution of one main lua state per thread.
The array introduces storage of one reference per thread, because each
lua state can have different reference id for a same function. A function
returns the preferred state id according to configuration and current
thread id.
The goal is to allow execution of one main lua state per thread.
"state_from" is a pointer to the parent lua state. "state_id"
is the index of the parent state id in the reference lua states
array. "state_id" is better because the lock is a "== 0" test
which is quick than pointer comparison. In other way, the state_id
index could index other things the the Lua state concerned. I
think to the function references.
The goal is to allow execution of one main lua state per thread.
This function will initialize the struct with other things than 0.
With this function helper, the initialization is centralized and
it prevents mistakes. This patch also keeps a reference to each
declared function in a list. It will be useful in next patches to
control consistency of declared references.
The goal is to allow execution of one main lua state per thread.
The array of states is initialized at the max number of thread +1.
We define the index 0 is the common state shared by all threads
and should be locked. Other index index are dedicated to each
one thread. The old gL now becomes hlua_states[0].
The goal is to allow execution of one main lua state per thread.
This patch opens the way to addition of a per-thread dedicated lua state.
By passing the hlua we can figure the original state that's been used
and decide to lock or not.
The goal is to allow execution of one main lua state per thread.
Stop using locks in init part, we will use only in parts where
the parent lua state is known, so we could take decision about lock
according with the lua parent state.
The goal is to allow execution of one main lua state per thread.
This commit introduces this variable in the core. Lua state initialized
by thread will have access to this variable, which reports the executing
thread. 0 indicates the shared thread. Programs which must be executed
only once can check for core.thread <= 1.
The goal is to allow execution of one main lua state per thread.
This function will be called for each initialized lua state, so
one per thread. The split transforms the lua state variable from
global to local.
The goal is to allow execution of one main lua state per thread.
This function will be called once per thread, using different Lua
states. This patch prepares the work.
The goal is to allow execution of one main lua state per thread.
The function hlua_ctx_init() now gets the original lua state from
its caller. This allows the initialisation of lua_thread (coroutines)
from any master lua state.
The parent lua state is stored in the hlua struct.
This patch is a temporary transition, it will be modified later.
The goal is to allow execution of one main lua state per thread.
This is a preparative work in order to init more than one stack
in the lua-thread objective.
The goal is to allow execution of one main lua state per thread.
Because this struct will be filled after the configuration parser, we
cannot copy the content. The actual state of the Haproxy code doesn't
justify this change, it is an update preparing next steps.
The goal is to no longer use "struct hlua" with global main lua_state.
The usage of the "struct hlua" is no longer required. This patch replaces
this struct by another one.
Now, the usage of runtime Lua phase is separated from the start lua phase.
The goal is to no longer use "struct hlua" with global main lua_state.
This patch returns NULL value when some code tries go get the hlua struct
associated with a task through hlua_gethlua(). This functions is useful
only during runtime because the struct hlua contains only runtime states.
Some Lua functions allowed to yield are called from init environment.
I'm not sure this is a good practice. Maybe it will be clever to
disallow calling this kind of functions.
The goal is no longer using "struct hlua" with global main lua_state.
if somewhere in the code, hlua_ctx_renew() is called with a global Lua
context, we have a serious bug. A crash is better than working with
this bug, so this patch remove a useless control.
In other way, this control were used during hlua_post_init() function.
The function hlua_post_init() used a call to the runtime hlua_ctx_resume()
function. This call no longer exists.
The goal is to no longer use "struct hlua" with global main lua_state.
The hlua_post_init() is executed during start phase, it does not require
yielding nor any advanced runtime error processing. Let's simplify this
by re-implementing the code using lower-level functions which directly
take a state and not an hlua anymore.
The goal is to no longer use "struct hlua" with global main lua_state
and directly take the state instead.
This patch removes the implicit dependency to this struct with
the function hlua_prepend_path()
Let's switch memory accounting to atomics so that the allocator function
may safely be used from concurrent Lua states.
Given that this function is extremely hot on the call path, we try to
optimize it for the most common case, which is:
- no limit
- there's enough memory
The accounting is what is particuarly expensive in threads since all
CPUs compete for a cache line, so when the limit is not used, we don't
want to use accounting. However we need to preserve it during the boot
phase until we may parse a "tune.lua.maxmem" value. For this, we turn
the unlimited "0" value to ~0 at the end of the boot phase to mark the
definite end of accounting. The function then detects this value and
directly jumps to realloc() in this case.
When the limit is enforced however, we use a CAS to check and reserve
our share of memory, and we roll back on failure. The CAS is used both
for increments and decrements so that a single operation is enough to
update the counters.
The function really has the semantics of a realloc() except that it
also passes the old size to help with accounting. No need to special
case the free or malloc, realloc does everything we need.
Lua allows registering multiple sample-fetches, converters, action, cli,
applet/services with the same name. This is absolutely useless since only
the first registration will be used. This patch sends a warning if the case
is encountered.
This pach could be backported until 1.8, with the 3 associated patches:
- MINOR: actions: Export actions lookup functions
- MINOR: actions: add a function returning a service pointer from its name
- MINOR: cli: add a function to look up a CLI service description
Operation luaL_openlibs() and lua_prepend path are processed whithout
the safe context, so in case of failure Haproxy aborts or stops without
error message.
This patch could be backported until 1.8
"lua-load" doesn't check if the expected parameter is present. It tries to
open() directly the argument at second position. So if the filename is
omitted, it tries to load an empty filename.
This patch could be backported until 1.8
This size is used by some pattern matching to determine if there
is sufficient room in the buffer to add final \0 if necessary.
If the size is not set, the conditions use uninitialized value.
Note: it seems this bug can't cause a crash.
Should be backported until 2.2 (at least)
Memset the sample before using it through hlua_lua2smp. This function is
ORing the smp.flags, so this field need to be cleared before its use.
This was reported by a coverity warning.
Fixes the github issue #929.
This bug can be backported up to 1.8.
Roughly half of the calls to sockadr_alloc() are made to copy an already
known address. Let's optionally pass it in argument so that the function
can handle the copy at the same time, this slightly simplifies its usage.
Debug Messages emitted in lua using core.Debug() or core.log() are now only
displayed on stderr if HAProxy is started in debug mode (-d parameter on the
command line). There is no change for other message levels.
This patch should fix the issue #879. It may be backported to all stable
versions.
We'll need this so that it can return pointers to stacked protocol in
the future (for QUIC). In addition this removes a lot of tests for
protocol validity in the callers.
Some of them were checked further apart, or after a call to
str2listener() and they were simplified as well.
There's still a trick, we can fail to return a protocol in case the caller
accepts an fqdn for use later. This is what servers do and in this case it
is valid to return no protocol. A typical example is:
server foo localhost:1111
If a file descriptor was passed, we can optionally return it. This will
be useful for listening sockets which are both a pre-bound FD and a ready
socket.
These flags indicate whether the call is made to fill a bind or a server
line, or even just send/recv calls (like logs or dns). Some special cases
are made for outgoing FDs (e.g. pipes for logs) or socket FDs (e.g external
listeners), and there's a distinction between stream or dgram usage that's
expected to significantly help str2sa_range() proceed appropriately with
the input information. For now they are not used yet.
Now that str2sa_range() checks for appropriate port specification, we
don't need to implement adhoc test cases in every call place, if the
result is valid, the conditions are met otherwise the error message is
appropriately filled.
These flags indicate what is expected regarding port specifications. Some
callers accept none, some need fixed ports, some have it mandatory, some
support ranges, and some take an offset. Each possibilty is reflected by
an option. For now they are not exploited, but the goal is to instrument
str2sa_range() to properly parse that.

This way, all fields of the buffer structure are reset when a string argument
(ARGT_STR) is released. It is also a good way to explicitly specify this kind
of argument is a chunk. So .data and .size fields must be set.
This patch may be backported to ease backports.
It means now regsub() converter is now exported to the lua. Map converters based
on regex are not available because the map arguments are not supported.
Thanks to previous commits, it is now safe to use from lua the sample fetches
and sample converters that convert arguments, especially the strings
(ARGT_STR). So now, there are all exported to the lua. They was filtered on the
validation functions. Only fetches without validation functions or with val_hdr
or val_payload_lv functions were exported, and converters without validation
functions.
This patch depends on following commits :
* aec27ef44 "BUG/MINOR: lua: Duplicate lua strings in sample fetches/converters arg array"
* fdea1b631 "MINOR: hlua: Don't needlessly copy lua strings in trash during args validation"
It must be backported as far as 2.1 because the date() and http_date()
converters are no longer exported because of the filter on the validation
function, since the commit ae6f125c7 ("MINOR: sample: add us/ms support to
date/http_date)".
Strings in the argument array used by sample fetches and converters must be
duplicated. This is mandatory because, during the arguments validations, these
strings may be converted and released. It works this way during the
configuration parsing and there is no reason to adapt this behavior during the
runtime when a sample fetch or a sample converter is called from the lua. In
fact, there is a reason to not change the behavior. It must reamain simple for
everyone to add new fetches or converters.
Thus, lua strings are duplicated. It is only performed at the end of the
hlua_lua2arg_check() function, if the argument is still a ARGT_STR. Of course,
it requires a cleanup loop after the call or when an error is triggered.
This patch depends on following commits:
* 959171376 "BUG/MINOR: arg: Fix leaks during arguments validation for fetches/converters"
* fdea1b631 "MINOR: hlua: Don't needlessly copy lua strings in trash during args validation"
It may be backported to all supported versions, most probably as far as 2.1
only.
Lua strings are NULL terminated. So in the hlua_lua2arg_check() function, used
to check arguments against the sample fetches specification, there is no reason
to copy these strings in a trash to add a terminating null byte.
In addition, when the array of arguments is built from lua values, we must take
care to count this terminating null bytes in the size of the buffer where a
string is stored. The same must be done when a sample is built from a lua value.
This patch may be backported to easy backports.
In hlua_lua2arg_check() function, before converting an argument to an IPv4 or
IPv6 mask, we must be sure to have an integer or a string argument (ARGT_SINT or
ARGT_STR).
This patch must be backported to all supported versions.
In hlua_lua2arg_check() function, before converting a string to an IP address,
we must be to sure to have a string argument (ARGT_STR).
This patch must be backported to all supported versions.
When a new map is created, the sample_load_map() function is called. To do so,
an argument array is created with the name as first argument. Because it is a
lua string, owned by the lua, it must be duplicated. The sample_load_map()
function will convert this argument to a map. In theory, after the conversion,
it must release the original string. It is not performed for now and it is a bug
that will be fixed in the next commit.
This patch may be backported to all supported versions, most probably as far as
2.1 only. But it must be backported with the next commit "BUG/MINOR: arg: Fix
leaks during arguments validation for fetches/converters".
This bug was introduced by the commit 8f587ea3 ("MEDIUM: lua: Set the analyse
expiration date with smaller wake_time only"). At the end of hlua_action(), the
lua context may be null if the alloc failed.
No backport needed, this is 2.3-dev.
If a lua action yields for any reason and if the wake timeout is set, it only
override the analyse expiration date if it is smaller. This way, a lower
inspect-delay will be respected, if any.
A Lua action may yield. It may happen because the action returns explicitly
act.YIELD or because the script itself yield. In the first case, we must abort
the script execution if it is the final rule evaluation, i.e if the
ACT_OPT_FINAL flag is set. The second case is already covered.
This patch must be backported to 2.2.
On Lua 5.4, some API changes make HAProxy compilation to fail. Among other
things, the lua_resume() function has changed and now takes an extra argument in
Lua 5.4 and the error LUA_ERRGCMM was removed. Thus the LUA_VERSION_NUM macro is
now tested to know the lua version is used and adapt the code accordingly.
Here are listed the incompatibilities with the previous Lua versions :

This patch comes from the HAproxy's fedora RPM, committed by Tom Callaway :
https://src.fedoraproject.org/rpms/haproxy/blob/db970613/f/haproxy-2.2.0-lua-5.4.patch
This patch should fix the issue #730. It must be backported to 2.2 and probably
as far as 2.0.
A workaround for some difficulties encountered to anticipate end of
messages was addressed by commit 810df0614 ("MEDIUM: htx: Add a flag on
a HTX message when no more data are expected"), but there were 3 issues
in it (with minor impact):
- the flag was mistakenly set before an EOH in Lua, which would only
cause incomplete packets to be emitted for now but could cause
truncated responses in the future. It's not needed to add it on
the next EOM block as http_forward_proxy_resp() already does it.
- one was still missing in hlua_applet_http_fct(), possibly causing
delays on Lua services
- one was missing in the Prometheus exporter.
All this simply shows that this mechanism is still quite fragile and
not trivial to use, especially in order to deal with the impossibility
to append the EOM, so we'll need to improve the solution in the future
and future backports should not be completely ruled out.
This fix must be backported where the patch above is backported,
typically 2.1 and later as it was required for a set of fixes.
The HTX_FL_EOI flag must now be set on a HTX message when no more data are
expected. Most of time, it must be set before adding the EOM block. Thus, if
there is no space for the EOM, there is still an information to know all data
were received and pushed in the HTX message. There is only an exception for the
HTTP replies (deny, return...). For these messages, the flag is set after all
blocks are pushed in the message, including the EOM block, because, on error,
we remove all inserted data.
Compiling HAProxy with USE_LUA=1 and running a configuration check within
valgrind with a very simple configuration such as:
listen foo
bind *:8080

==24048== still reachable: 329,960 bytes in 71 blocks
==24048== suppressed: 0 bytes in 0 blocks
Printing these possible leaks shows that all of them are caused by Lua.
Luckily Lua makes it *very* easy to free all used memory, so let's do
this on shutdown.
Afterwards this patch is applied the output looks much better:

Getting rid of this warning is cleaner solved using a 'fall through' comment,
because it clarifies intent to a human reader.
This patch adjust a few places that cause -Wimplicit-fallthrough to trigger:
- Fix typos in the comment.
- Remove redundant 'no break' that trips up gcc from comment.
- Move the comment out of the block when the 'case' is completely surrounded
by braces.
- Add comments where I could determine that the fall through was intentional.

This patch fixes all the leftovers from the include cleanup campaign. There
were not that many (~400 entries in ~150 files) but it was definitely worth
doing it as it revealed a few duplicates.
Most of the files dealing with error reports have to include log.h in order
to access ha_alert(), ha_warning() etc. But while these functions don't
depend on anything, log.h depends on a lot of stuff because it deals with
log-formats and samples. As a result it's impossible not to embark long
dependencies when using ha_warning() or qfprintf().
This patch moves these low-level functions to errors.h, which already
defines the error codes used at the same places. About half of the users
of log.h could be adjusted, sometimes revealing other issues such as
missing tools.h. Interestingly the total preprocessed size shrunk by
4%.
There's no point splitting the file in two since only cfgparse uses the
types defined there. A few call places were updated and cleaned up. All
of them were in C files which register keywords.
There is nothing left in common/ now so this directory must not be used
anymore.
This one was not easy because it was embarking many includes with it,
which other files would automatically find. At least global.h, arg.h
and tools.h were identified. 93 total locations were identified, 8
additional includes had to be added.
In the rare files where it was possible to finalize the sorting of
includes by adjusting only one or two extra lines, it was done. But
all files would need to be rechecked and cleaned up now.
It was the last set of files in types/ and proto/ and these directories
must not be reused anymore.
extern struct dict server_name_dict was moved from the type file to the
main file. A handful of inlined functions were moved at the bottom of
the file. Call places were updated to use server-t.h when relevant, or
to simply drop the entry when not needed.
This one is particularly difficult to split because it provides all the
functions used to manipulate a proxy state and to retrieve names or IDs
for error reporting, and as such, it was included in 73 files (down to
68 after cleanup). It would deserve a small cleanup though the cut points
are not obvious at the moment given the number of structs involved in
the struct proxy itself.
It was moved without any change, however many callers didn't need it at
all. This was a consequence of the split of proto_http.c into several
parts that resulted in many locations to still reference it.
Almost no change except moving the cli_kw struct definition after the
defines. Almost all users had both types&proto included, which is not
surprizing since this code is old and it used to be the norm a decade
ago. These places were cleaned.
Just some minor reordering, and the usual cleanup of call places for
those which didn't need it. We don't include the whole tools.h into
stats-t anymore but just tools-t.h.
The type file was slightly tidied. The cli-specific APPCTX_CLI_ST1_* flag
definitions were moved to cli.h. The type file was adjusted to include
buf-t.h and not the huge buf.h. A few call places were fixed because they
did not need this include.
The type file is becoming a mess, half of it is for the proxy protocol,
another good part describes conn_streams and mux ops, it would deserve
being split again. At least it was reordered so that elements are easier
to find, with the PP-stuff left at the end. The MAX_SEND_FD macro was moved
to compat.h as it's said to be the value for Linux.
The TASK_IS_TASKLET() macro was moved to the proto file instead of the
type one. The proto part was a bit reordered to remove a number of ugly
forward declaration of static inline functions. About a tens of C and H
files had their dependency dropped since they were not using anything
from task.h.
This one is particularly tricky to move because everyone uses it
and it depends on a lot of other types. For example it cannot include
arg-t.h and must absolutely only rely on forward declarations to avoid
dependency loops between vars -> sample_data -> arg. In order to address
this one, it would be nice to split the sample_data part out of sample.h.
There's no type file, it only contains fetch_rdp_cookie_name() and
val_payload_lv() which probably ought to move somewhere else instead
of staying there.
It was moved as-is, except for extern declaration of pattern_reference.
A few C files used to include it but didn't need it anymore after having
been split apart so this was cleaned.
A few includes had to be added, namely list-t.h in the type file and
types/proxy.h in the proto file. actions.h was including http-htx.h
but didn't need it so it was dropped.
And also rename standard.c to tools.c. The original split between
tools.h and standard.h dates from version 1.3-dev and was mostly an
accident. This patch moves the files back to what they were expected
to be, and takes care of not changing anything else. However this
time tools.h was split between functions and types, because it contains
a small number of commonly used macros and structures (e.g. name_desc)
which in turn cause the massive list of includes of tools.h to conflict
with the callers.
They remain the ugliest files of the whole project and definitely need
to be cleaned and split apart. A few types are defined there only for
functions provided there, and some parts are even OS-specific and should
move somewhere else, such as the symbol resolution code.
The file was moved as-is. There was a wrong dependency on dynbuf.h
instead of buf.h which was addressed. There was no benefit to
splitting this between types and functions.
The type is the only element needed by applet.h and hlua.h, while hlua.c
needs the various functions. XREF_BUSY was placed into the types as well
since it's better to have the special values there.
Regex are essentially included for myregex_t but it turns out that
several of the C files didn't include it directly, relying on the
one included by their own .h. This has been cleanly addressed so
that only the type is included by H files which need it, and adding
the missing includes for the other ones.
Some of them were simply removed as unused (possibly some leftovers
from an older cleanup session), some were turned to haproxy/bitops.h
and a few had to be added (hlua.c and stick-table.h need standard.h
for parse_time_err; htx.h requires chunk.h but used to get it through
standard.h).
This splits the hathreads.h file into types+macros and functions. Given
that most users of this file used to include it only to get the definition
of THREAD_LOCAL and MAXTHREADS, the bare minimum was placed into thread-t.h
(i.e. types and macros).
All the thread management was left to haproxy/thread.h. It's worth noting
the drop of the trailing "s" in the name, to remove the permanent confusion
that arises between this one and the system implementation (no "s") and the
makefile's option (no "s").
For consistency, src/hathreads.c was also renamed thread.c.
A number of files were updated to only include thread-t which is the one
they really needed.
Some future improvements are possible like replacing empty inlined
functions with macros for the thread-less case, as building at -O0 disables
inlining and causes these ones to be emitted. But this really is cosmetic.
All files that were including one of the following include files have
been updated to only include haproxy/api.h or haproxy/api-t.h once instead:
- common/config.h
- common/compat.h
- common/compiler.h
- common/defaults.h
- common/initcall.h
- common/tools.h
The choice is simple: if the file only requires type definitions, it includes
api-t.h, otherwise it includes the full api.h.
In addition, in these files, explicit includes for inttypes.h and limits.h
were dropped since these are now covered by api.h and api-t.h.
No other change was performed, given that this patch is large and
affects 201 files. At least one (tools.h) was already freestanding and
didn't get the new one added.
This is where other imported components are located. All files which
used to directly include ebtree were touched to update their include
path so that "import/" is now prefixed before the ebtree-related files.
The ebtree.h file was slightly adjusted to read compiler.h from the
common/ subdirectory (this is the only change).
A build issue was encountered when eb32sctree.h is loaded before
eb32tree.h because only the former checks for the latter before
defining type u32. This was addressed by adding the reverse ifdef
in eb32tree.h.
No further cleanup was done yet in order to keep changes minimal.
