Hiltjo Posthuma e45e64491e Only check errno if getpwuid() fails 
Checking errno otherwise is unspecified.

Hiltjo Posthuma 96f15f1d04 errno: check only errno if return value was NULL 2014-07-09 15:07:34 +01:00
Hiltjo Posthuma 528f10be6c util/passwd.c: check errno only if spw is NULL 
this is more reliable. there is a difference between glibc and musl
errno if /etc/tcb/<name>/shadow doesn't exist.

sin 10c8b71fd2 Kick off respawn in its own session 2014-07-06 21:36:28 +01:00
sin ce59961f19 respawn: kill child process upon SIGTERM 
We might revisit this and be more strict i.e. kill the child
process even if it is in a new process session/group.

For now this is probably a good enough balance.

This patch changes the existing semantics of respawn, the child
process is now part of the same process session as respawn.

Hiltjo Posthuma 5a06a9f7e1 pidof: match on full name and basename 
busybox doesn't do this, but procps does.

sin 55dd1076fe Print header after trying to open /proc/modules 
This fails on kernels compiled without module support or
if procfs is not mounted.

sin 643a714256 Simplify dmesg_show() 
The code was way too complicated.  We do not currently filter out
the priority level, so we default to raw output.

sin b5c3bcda7d Ensure that path[0] == '\0' upon entry to delete_content() 
As a quick fix, staticise path to ensure that it is zero-filled
upon initial entry to the function.

In rare cases there's a possible buffer overflow and/or path
mess up on the first call to strlcat() with path[0] != '\0'.

The proper fix is to utilize util/recurse.c but the traversal
order cannot be specified at the moment.

Expect a better fix in the future.
