Allow an alternate libc, such as dietlibc, to be used for the init binary in the supermin appliance. Rich.

...al: buffer_append_space: alloc 10506240 not supported" anytime privsep is on and compression is on. After some digging, we were able to trace the problem to "buffer_uncompress" in compress.c - it seems that in some circumstances the inflate call returns Z_OK and incoming_stream.avail_out == 0, thus the program alloc's another sizeof(buf)-0 = 4096 bytes for the output_buffer, then repeats the call to inflate, which again returns status==0 and avail_out==0, thus entering an infinite loop. This is what happens under strace: =====[cut here]===== [pid 8379] old_mmap(NULL, 151...

Joseph, Please try my modified versions of these patches. These are compile-tested on Fedora and they don't break any existing functionality, but I don't have either urpmi nor a statically-linked xz so I cannot fully test them. I have also fixed detection of zlib (2/3). Rich.

Hi, the two patches improve the way memory is handled in supermin, by cleanly exiting on memory allocation failures, and free'ing memory when not needed (to keep working and not run out of memory).

v1 -> v2: - If we split out the init program into a separate init/ directory, that makes it much easier to build against an alternate libc. I tried to build against uClibc, but uClibc requires an entire build chain, which looked like it was going to be a massive ballache. Rich.

I am running the following rsync command to synchronize directories between two servers: rsync -axvz --delete-after -e ssh /SRCDIR/ blabla at DEST:/DESTDIR The transfer starts and after a short while it appears to hang after some files have been transferred.

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address

I hacked zstd support into OpenSSH a while ago and just started to clean it up in the recent days. The cleanup includes configuration support among other things that I did not have. During testing I noticed the following differences compared to zlib: - highly interactive shell output (as in refreshed at a _very_ high rate) may result in higher bandwidth compared to zlib. Since zstd is quicker

> Just curious: what about the rsync+ patch? Thanks for the reminder. I've just committed Jos's rsync+ patch onto the "branch_mbp_rsyncplus_merge" branch. If it works OK and nobody screams I will move it across onto the main tree tomorrow or Wednesday. I see the patch doesn't add documentation about the new options to the man page, so we should fix that in the future.
