[PATCH] libvirt_nss: Fix ERROR() macro
by Michal Privoznik 18 Apr '24

18 Apr '24

The purpose of ERROR() macro in our NSS module is to print error message provided as arguments followed by error string corresponding to errno. Historically, we've used strerror_r() for that (please note, we want our NSS module to be free of libvirt internal functions, or glib even - hence, g_strerror() is off the table). Now strerror_r() is documented as: Returns ... a pointer to a string that the function stores in buf, or a pointer to some (immutable) static string (in which case buf is unused). Therefore, we can't rely the string being stored in the buf and really need to store the retval and print that instead. While touching this area, decrease the ebuf size, since its current size (1KiB) is triggering our stack limit (2KiB) in some cases.

[PATCH] qemu: Use g_autoptr in qemuProcessInit
by Jiri Denemark 16 Apr '24

16 Apr '24

The only thing we need to free in the cleanup code is virCPUDef and for that we already have g_autoptr handler.

[PATCH v3 20/22] hw/i386/pc: Remove deprecated pc-i440fx-2.3 machine

The pc-i440fx-2.3 machine was deprecated for the 8.2 release (see commit c7437f0ddb "docs/about: Mark the old pc-i440fx-2.0 - 2.3 machine types as deprecated"), time to remove it.
