audit: Fix compile error for audit_2.8.5
Fix below compile errors
1. Fix build with linux 5.17+
audit errors out due to swig munging it does with kernel headers
| audit_wrap.c: In function '_wrap_audit_rule_data_buf_set':
| audit_wrap.c:4701:17: error: cast specifies array type
| 4701 | arg1->buf = (char [])(char *)memcpy(malloc((size)*sizeof(char)), (const char *)(arg2), sizeof(char)*(size));
| | ^
| audit_wrap.c:4701:15: error: invalid use of flexible array member
| 4701 | arg1->buf = (char [])(char *)memcpy(malloc((size)*sizeof(char)), (const char *)(arg2), sizeof(char)*(size));
| | ^
| audit_wrap.c:4703:15: error: invalid use of flexible array member
| 4703 | arg1->buf = 0;
| | ^
These errors are due to VLAIS from kernel headers, so we copy
linux/audit.h and make the needed change in local audit.h and make
needed arrangements in build to use it when building audit package
Take reference of upstream commit
ee3c680c3 audit: Upgrade to 3.0.8 and fix build with linux 5.17+
Update 0002-Fixed-swig-host-contamination-issue.patch
2. Fix ipx.h missing file bug for kernel 5.15
ipx.h header file is removed in kernel 5.15
Link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/include/net?id=6c9b40844751ea30c72f7a2f92f4d704bc6b2927
which is causing below error for system with kernel equal and
higher than 5.15
| ../../git/auparse/interpret.c:48:10: fatal error: linux/ipx.h: No such file or directory
| 48 | #include <linux/ipx.h>
| | ^~~~~~~~~~~~~
Add below patch to fix this issue.
