Donenfeld <Jason@zx2c4.com> # Date: Sun Jun 21 21:02:22 2020 -0600 # # Revert "kernel/printk: add kmsg SEEK_CUR handling" # # This reverts commit 8ece3b3eb576a78d2e67ad4c3a80a39fa6708809. # # This commit broke userspace. Bash uses ESPIPE to determine whether or # not the file should be read using "unbuffered I/O", which means reading # 1 byte at a time instead of 128 bytes at a time. I used to use bash to # read through kmsg in a really quite nasty way: # # while read -t 0.1 -r line 2>/dev/null \|\| [[ $? -ne 142 ]]; do # echo "SARU $line" # done < /dev/kmsg # # This will show all lines that can fit into the 128 byte buffer, and skip # lines that don't. That's pretty awful, but at least it worked. # # With this change, bash now tries to do 1-byte reads, which means it # skips all the lines, which is worse than before. # # Now, I don't really care very much about this, and I'm already look for # a workaround. But I did just spend an hour trying to figure out why my # scripts were broken. Either way, it makes no difference to me personally # whether this is reverted, but it might be something to consider. If you # declare that "trying to read /dev/kmsg with bash is terminally stupid # anyway," I might be inclined to agree with you. But do note that bash # uses lseek(fd, 0, SEEK_CUR)==>ESPIPE to determine whether or not it's # reading from a pipe. # # Cc: Bruno Meneguele <bmeneg@redhat.com> # Cc: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> # Cc: Steven Rostedt <rostedt@goodmis.org> # Cc: David Laight <David.Laight@ACULAB.COM> # Cc: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> # Cc: Petr Mladek <pmladek@suse.com> # Signed-off-by: Jason A.
