Patch adds 1 second waiting for socket buffer can accept the message, helps when syslogd is working hard. If it's stalled/SIGSTOPed, message will be sent to errout as before. After that, further non-blocking /dev/log connect attempts will fail immediately with EAGAIN error until syslogd reads some from it. function old new delta openlog_intern 259 355 +96 static.tv - 8 +8 .rodata 151 159 +8 ------------------------------------------------------------------------------ (add/remove: 1/0 grow/shrink: 2/0 up/down: 112/0) Total: 112 bytes Signed-off-by: Vladislav Grishenko <themiron(a)mail.ru> commit 64917add7f4aeec8720d2fba5e96ea39aac35623 Author: Vladislav Grishenko <themiron(a)mail.ru> Date: Wed Sep 12 17:13:55 2012 +0600 Fix syslog messages lost after syslogd restarts If syslogd is stopped and restarted while a process has the log open, the next message that process produces will be logged to the console and not to the new instance of syslogd.

revert GLIBC_MINOR bump in uClibc-ng 1.0 branch
by Waldemar Brodkorb 14 Dec '15

14 Dec '15

Hi Thomas, Khem, Alexey, recently Khem tried to use systemd with openembedded and uClibc-ng. Most of the needed stuff is ready and will be committed soon. There is one open issue I want to discuss with you. The GLIBC_MINOR bump in commit 4a05ed87ceb946608100642121c32e642b58cd0d is breaking SSP detection in GCC. This was discovered in Buildroot and fixed. It seems there is a major problem to fix it in OpenEmbedded, so Khem is asking for revert of this commit for the next release. What do you think about it? Isn't the boost problem solved anyway in another way? May be we just learned what it means to bump this number and can revert it back to the old value. We should still try to get a patch into gcc to avoid any misdetection regarding SSP for the next major gcc release. Thanks for any opinion, best regards Waldemar

[PATCH] config: allow config to handle longer path names
by Markus Mayer 11 Dec '15

11 Dec '15

The current (arbitrary) limit of 128 characters for path names has proven too short for Android builds, as longer path names are used there. Change conf.c, so it can handle path lengths up to PATH_MAX characters.
