perf-annotate(1) ================ NAME ---- perf-annotate - Read perf.data (created by perf record) and display annotated code SYNOPSIS -------- [verse] 'perf annotate' [-i | --input=file] [symbol_name] DESCRIPTION ----------- This command reads the input file and displays an annotated version of the code. If the object file has debug symbols then the source code will be displayed alongside assembly code. If there is no debug info in the object, then annotated assembly is displayed. OPTIONS ------- -i:: --input=:: Input file name. (default: perf.data unless stdin is a fifo) -d:: --dsos=:: Only consider symbols in these dsos. -s:: --symbol=:: Symbol to annotate. -f:: --force:: Don't do ownership validation. -v:: --verbose:: Be more verbose. (Show symbol address, etc) -D:: --dump-raw-trace:: Dump raw trace in ASCII. -k:: --vmlinux=:: vmlinux pathname. -m:: --modules:: Load module symbols. WARNING: use only with -k and LIVE kernel. -l:: --print-line:: Print matching source lines (may be slow). -P:: --full-paths:: Don't shorten the displayed pathnames. --stdio:: Use the stdio interface. --stdio-color:: 'always', 'never' or 'auto', allowing configuring color output via the command line, in addition to via "color.ui" .perfconfig. Use '--stdio-color always' to generate color even when redirecting to a pipe or file. Using just '--stdio-color' is equivalent to using 'always'. --tui:: Use the TUI interface. Use of --tui requires a tty, if one is not present, as when piping to other commands, the stdio interface is used. This interfaces starts by centering on the line with more samples, TAB/UNTAB cycles through the lines with more samples. --gtk:: Use the GTK interface. -C:: --cpu:: Only report samples for the list of CPUs provided. Multiple CPUs can be provided as a comma-separated list with no space: 0,1. Ranges of CPUs are specified with -: 0-2. Default is to report samples on all CPUs. --asm-raw:: Show raw instruction encoding of assembly instructions. --source:: Interleave source code with assembly code. Enabled by default, disable with --no-source. --symfs=:: Look for files with symbols relative to this directory. -M:: --disassembler-style=:: Set disassembler style for objdump. --objdump=:: Path to objdump binary. --skip-missing:: Skip symbols that cannot be annotated. --group:: Show event group information together SEE ALSO -------- linkperf:perf-record[1], linkperf:perf-report[1] alue=''/>

net: ipv4: dst for local input routes should use l3mdev if relevant
IPv4 output routes already use l3mdev device instead of loopback for dst's if it is applicable. Change local input routes to do the same. This fixes icmp responses for unreachable UDP ports which are directed to the wrong table after commit 9d1a6c4ea43e4 because local_input routes use the loopback device. Moving from ingress device to loopback loses the L3 domain causing responses based on the dst to get to lost. Fixes: 9d1a6c4ea43e4 ("net: icmp_route_lookup should use rt dev to determine L3 domain") Signed-off-by: David Ahern <dsa@cumulusnetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
