Background: OpenAFS is vulnerable to crashing in the linux kernel symlink
code when running on kernel versions between 2.6.10 to 2.6.12. This also
includes all RHEL4 kernels, because RHEL4 includes the code from 2.6.10. The
problem is that the symlink text caching API, page_follow_link() et al, is
unsuitable for network filesystems where the page cache may be invalidated
in parallel with a path lookup.
This crash can be triggered easily by doing a bunch of path lookups
involving symlinks (e.g., stat() on various files pointed to through links),
while simultaneously running 'fs flushvol' on the volume containing the
symlinks.
The simplest way to fix this problem is to disable the use of symlink text
caching when the kernel does not provide a usable symlink API.
FIXES 40604
Test whether Linux kernel builds work at all before going into specific
builds so that we can fail earlier with a better error message. Try to
put more errors from the kernel build into config.log.
Rather than setting AFS_PARAM_COMMON as part of the sysname guessing code,
guess the sysname first and then sent AFS_PARAM_COMMON in a separate case
statement based on the results. Otherwise, it isn't set when
--with-afs-sysname is used explicitly, resulting in a broken Linux build.
Add a shared libkopenafs that provides k_hasafs, k_setpag, k_unlog, and
k_pioctl (in other words, enough for a PAM session module that calls an
external aklog).
