Subject: Linux 2.4.36-rc1

I've just released Linux 2.4.36-rc1.

It fixes several vulnerabilities, some of them discovered in 2.6.
Among them, we find 2 ISDN overflows, one case of insufficient
permissions checking on core dumps, the ability for a process to
escape ptrace-based syscall policy checking, and the possibility
for a specially crafted ELF binary to bypass the recently added
restrictions on the minimum MMAP address.

Due to several reports of mis-compilations with GCC 4.2, I have
explicitly disabled its use with an explicit message.

I got one report from Krzysztof Strasburger of a good old 386 not
booting anymore due to a misplaced "HAS_TSC" in the config. His
fix made perfect sense and looked good, but please complain if you
notice a related problem on old hardware.

It was also not possible to build for ia32 on x86_64 due to a
recent vulnerability fix in which an update to the size of the
instruction was missing (cmpl -> cmpq).

I'm still planning on releasing 2.4.36 around the end of the year
(eg: last week-end), if nothing new is discovered since. If new
fixes are merged by that time, I may delay it a little bit to the
beginning of January.

Please test it, beat it and report any problems (build or bugs).

The patch and changelog will appear soon at the following locations:
