Patch for boot-time USB hangs in 4.9-PRERELEASE
...subr_taskqueue.c case, there is also a call to kthread_create() in the USB code, so that might be related too. Apply the patch in /usr/src/sys/kern, then rebuild the kernel and reboot.

[dillon@FreeBSD.org: cvs commit: src/sys/net zlib.c]
...when the kernel PPP / DEFLATE code is used. 1.11 moved a ZFREE to a point after the structural members were clobbered by stores into a union'd structure. This commit fixes the bug and adds a big whopping comment to make sure the code isn't 'cleaned up' again :-) Ian Dowse came up with the same patch independantly 68 seconds before I did, talk about Karma! I would also like to thank Eugene Grosbein for marathon work in tracking the problem down by udpating his -stable based on date over and over again to close in on the commit that caused his crashes....

Bigcrypt password patch
Hi, we are currently in the progress of switching an HPUX mailserver to linux and dovecot. The only issue so far is, that HPUX has bigcrypt for passwords > 8 chars. Bigcrypt uses standard libc crypt for every block of 8 chars. The linux pam modules have a bigcrypt.c file which can be used for dovecot as well to authenticate crypt and bigcrypt passwords. I have used the pam bigcrypt.c code

Fwd: Problem of array index manipulation collection of LLVM IR
Hi there, I am a newbie of llvm and here is my question situation. Assume that there is a function F which contains a loop named L, a array b[100]. I want to collect the statistical information of array index operation op(i) (take add and mul simply) of i in the loop L. Pseudocode lists below. void F(arg1, arg2){ int b[100]; for(int i=0; i<n; i++){ op1(i); op2(i);

PATCH: Forcible delaying of UFS (soft)updates
Here's a patch against 4.8-RELEASE kernel that allows disk writes on softupdates-enabled filesystems to be delayed for (theoretically) arbitrarily long periods of time. The motivation for such updating policy is surprisingly not purely suicidal - it can allow disks on laptops to spin down immediately after I/O operations and stay idle for longer periods of time, thus saving considerable amount
