And on new kernels you still cannot +# guarantee to grab the zero id for testing; the id might be in use by +# some other process, or the kernel might just not give out that id +# for some other reason. +# +# To figure out which mappings to include in the core file, GDB reads +# the /proc/PID/smaps file. There is a field in this file which for +# file backed mappings, holds the inode of the file. But for shared +# memory mappings this field holds the shared memory id. The problem +# was that GDB would ignore any entry in /proc/PID/smaps with an inode +# entry of zero, which would catch the shared memory mapping with a +# zero id. +# +# There was an attempt to write a test which spammed out requests for +# shared memory mappings and tried to find the one with id zero, but +# this was still really unreliable. +# +# This test takes a different approach. We compile a library which we +# preload into the GDB process. This library intercepts calls to +# open, close, read, and pread, and watches for an attempt to open the +# /proc/PID/smaps file. +# +# When we see that file being opened, we copy the file contents into a +# memory buffer and modify the buffer so that the inode field for any +# shared memory mappings is set to zero. We then intercept calls to +# read and pread and return results from that in memory buffer. +# +# The test executable itself create a shared memory mapping (which +# might have any id). +# +# GDB, with the pre-load library in place, start the inferior and then +# uses the 'gcore' command to dump a core file.
