FreeIPMI provides in-band and out-of-band IPMI software based on the IPMI v1.5/2.0 specification. The IPMI specification defines a set of interfaces for platform management and is implemented by a number of vendors for system management. The features of IPMI that most users will be interested in are sensor monitoring, system event monitoring, power control, and serial-over-LAN (SOL). The FreeIPMI tools and libraries listed below should provide users with the ability to access and utilize these and many other features. A number of useful features for large HPC or cluster environments have also been implemented into FreeIPMI. Signed-off-by: Bjørn Mork <bjorn@mork.no>

Subject: [PATCH] libipmiconsole: set minimum stacksize to avoid SEGFAULT with
|
|
musl

libipmiconsole SEGFAULTs with musl because the default stacksize
|
|
is too small.
|
|
|
|
This fix is inspired by
|
|
|
|
mail/sendmail/patches/102-pthreads-stack-size.patch
|
|
|
|
having the following description:
|
|
|
|
"This patch increases the stack size for pthreads from 80 KB, the default
|
|
stack size for musl libc, to 2 MB. The default stack size for glibc is 8 MB.
|
|
|
|
OpenDKIM, an application that depends on libmilter, segfaults if the stack
|
|
size for pthreads is left unchanged at the musl default value of 80 KB.
|
|
Apparently, OpenDKIM allocates blocks of 64 KB multiple times, which causes
|
|
libmilter and therefore OpenDKIM to crash:

|
|
|
|
This patch follows the patch suggested by an Alpine Linux user in bug report
|
|
above. Also, a bug report has been filed upstream:
|
|
https://sourceforge.net/p/opendkim/bugs/258/
