When tab-completing a command we search PATH if the partial text doesn't include a slash. Also match subdirectories of the current directory, in case the user intends to run a binary from one of them. function old new delta complete_cmd_dir_file 894 917 +23 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 23/0) Total: 23 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2020-12-15udhcp: bind to device even for ucast packetsMichal Kazior
There are cases where binding to source IP and destination IP is insufficient to guarantee sane xmit netdev. One case where this can fail is when route-matching netdev carrier is down (cable unplugged, wifi disconnected), or the netdev is admin down. Then all the IP based bindings (bind() + connect()) will seemingly succeed but the actual packet can go out through a default gw path. Depending on the network this happens on it can create issues or false alarms. It can also leak some subnet info across networks that shouldn't be routed. As such better be safe than sorry and bind to a netdev to be sure it's used for xmit. function old new delta udhcp_send_kernel_packet 293 336 +43 send_packet 182 188 +6 bcast_or_ucast 37 43 +6 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 55/0) Total: 55 bytes Signed-off-by: Michal Kazior <michal@plume.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

When mounting, in parallel, multiple loop devices (squashfs for the submitter's case), the following behavior can be observed: stat64(/path/to/image, {st_mode=S_IFREG|0644, st_size=4096, ...}) = 0 openat(AT_FDCWD, /path/to/image, O_RDWR|O_LARGEFILE) = 3 openat(AT_FDCWD, /dev/loop-control, O_RDWR|O_LARGEFILE|O_CLOEXEC) = 4 ioctl(4, LOOP_CTL_GET_FREE) = 12 close(4) = 0 openat(AT_FDCWD, /dev/loop12, O_RDWR|O_LARGEFILE) = 4 ioctl(4, LOOP_GET_STATUS64, {lo_offset=0, lo_number=12, lo_flags=LO_FLAGS_AUTOCLEAR, lo_file_name=/path/to/image, ...}) = 0 close(4) = 0 close(3) = 0 write(2, "mount: can't setup loop device\n", 31mount: can't setup loop device ) = 31 exit_group(0) = ? +++ exited with 0 +++ The ioctl LOOP_CTL_GET_FREE has resulted in the same result for a competing mount process. The subsequent ioctl LOOP_GET_STATUS64 fails, having succeeded for the competing mount process. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
