Description

abrt is the only thing by default that sets core_pattern - assigning there. The *tables errors are unfortunate due to the order of network module loading, and can't be avoided; it's why all scripted invocations of it use '-e'. This issue has been proposed when we are only considering blocker issues in the current Red Hat Enterprise Linux release. It has been denied for the current Red Hat Enterprise Linux release. ** If you would still like this issue considered for the current release, ask your support representative to file as a blocker on your behalf. Otherwise ask that it be considered for the next Red Hat Enterprise Linux release. ** Created bug 618602 - kernel's parameter length limit is too small to fix this bug.

Proposed patch
Since kernel-side fix (see bug 618602) is planned for inclusion in RHEL6 update, we are ready to fix it on abrt side too. Testing the fix for bug 614486 with kernel-2.6.32-83.el6. I set /proc/sys/kernel/core_pattern to: echo really_long_long_long_long_long_long_long_long_corename_s%s_c%c_p%p_u%u_g%g_t%t_h%h_e%e >/proc/sys/kernel/core_pattern When abrt starts, it sets core_pattern to: |/usr/libexec/abrt-hook-ccpp /var/spool/abrt %s %c %p %u %g %t %h %e 7265616c6c795f6c6f6e675f6c6f6e675f6c6f6e675f6c6f6e675f6c6f6e675f6c6f6e675f6c6f6e675f6c6f6e675f636f72656e616d655f7325735f6325635f7025705f7525755f6725675f7425745f6825685f652565 The long hex string is a hex-encoded "really_long_long_long_long_long_long_long_long_corename_s%s_c%c_p%p_u%u_g%g_t%t_h%h_e%e" But only "|/usr/libexec/abrt-hook-ccpp /var/spool/abrt %s %c %p %u %g %t %h %e 7265616c6c795f6c6f6e675f6c6f6e675f6c6f6e675f6c6f6e675f6c6f" makes it (127 chars). As a result, abrt-hook-ccpp saves coredump under truncated name "really_long_long_long_long_lo" I'd say that for most real-world cases it will work, but raising the 128 char limit would be appreciated. Fix is pushed to git, abrt_11x branch Created attachment 472076 [details]
