...PID 0, no file * space If I build the lsof binary under 4.8-STABLE, then it runs fine under 4.8-STABLE and 4-STABLE. Upon investigation it appears that the variable fd in the file dproc.c is being used uninitialized in gather_proc_info(). The problem seems to be related to some changes to struct filedesc (/usr/include/sys/filedesc.c) from some recent commits to the RELENG_4 branch on /usr/src/sys/sys/filedesc.c... Anyone care to investigate further? Geoffrey

...mparing stuff from two different partitions, etc. There was some discussion on whether the FAT library, should be in com32/lib, but its quite helpful for me since I can hook my own read_handler for any partition on any disk, and use libfat to read files off it. Here is an example: typedef struct filedesc { diskinfo* disk_info; part_entry* partition; } filedesc; static filedesc rFd; static int fat_disk_read_handle(intptr_t fdp, void* buf, size_t nbyte, libfat_sector_t sector) { filedesc* fd = (filedesc*) fdp; int num_sectors = nbyte / LIBFAT_SECTOR_SIZE; int status; sector += fd...

This is a repost of the patch I sent on Friday. I know it was already ACK'd, but I've changed a fair bit in addition to adding the requested POD. Specifically: I discovered that augeas's grub lens wasn't returning cmdline the way I expected. This is fixed. The kernel package, if known, is output as a property of the kernel. The XML output of virt-inspector is updated with all

Yesterday I begin a couple of update to the latest 4.8-STABLE. After that the two boxes continues to go in panics as soon as Apache (1.3 from the ports, also freshly recompiled, 2.0.x seems NOT to hang) starts. I don't know if it is related to the other thread : "Kernel core dump in recent 4.8-STABLE" but it is easily reproducible by cvsupping to a today -STABLE and then running

Hello Folks, Just a status on upcoming advisories. FreeBSD-SA-03:15.openssh This is in final review and should be released today. Fixes for this issue entered the tree on September 24. I apologize for the delay in getting this one out. FreeBSD-SA-03:16.filedesc A reference counting bug was discovered that could lead to kernel memory disclosure or a system panic. Fixes for this issue were committed to -CURRENT, -STABLE, and the security branches earlier today. This bug was reported to us by Joost Pol of Pine Digital Security, and...
