This patch does two things. This test program results (on i386) in an error about _NSIG: #include <signal.h> #if defined (SIGRTMAX) int rtmax = SIGRTMAX; #endif The cause is that the kernel signal.h defines SIGRTMAX as _NSIG, then makes _NSIG invisibelby hiding it inside ifdef __KERNEL__. Perhaps it's more elegant to solve this in the kernel, but the ramifications of t...

https://bugzilla.mindrot.org/show_bug.cgi?id=2619 Bug ID: 2619 Summary: infinite loop, 100% cpu use in ssh if ^Z is pressed at password prompt Product: Portable OpenSSH Version: 7.3p1 Hardware: Other OS: Linux Status: NEW Severity: enhancement Priority: P5 Component:

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code. This is also available as a git tree at:
