Re: [Crash-utility] [PATCH v2 1/3] Update gdb to 10.1

Hi Alexey, Thank you for the huge work! and sorry for the delayed response. Apparently updating gdb had been done only when kernel required it, but these days gdb-7.6 has some problems and is old enough, this update can make crash more useful and future proof. I need more time to finish reviewing the patches, but there are a few lacks of output from my test. Is it possible to fix the following? --- crash-master.log +++ crash-gdb-10.1.log * 'bt' command often emits reduced output: @@ -3391,13 +2885,6 @@ PID: 951 TASK: ffff880079489fa0 CPU: 0 COMMAND: "sshd" #0 [ffff88007997b888] __schedule at ffffffff816a8f45 #1 [ffff88007997b8f0] schedule at ffffffff816a94c9 - #2 [ffff88007997b900] schedule_hrtimeout_range_clock at ffffffff816a86dd - #3 [ffff88007997b998] schedule_hrtimeout_range at ffffffff816a8713 - #4 [ffff88007997b9a8] poll_schedule_timeout at ffffffff81215eb5 - #5 [ffff88007997b9d8] do_select at ffffffff81216831 - #6 [ffff88007997bd80] core_sys_select at ffffffff81216afb - #7 [ffff88007997bf18] sys_select at ffffffff81216cda - #8 [ffff88007997bf80] system_call_fastpath at ffffffff816b4fc9 RIP: 00007f04a6bd4783 RSP: 00007fffd1652898 RFLAGS: 00000246 RAX: 0000000000000017 RBX: ffffffff816b4fc9 RCX: ffffffffffffffff RDX: 0000000000000000 RSI: 000055d9679059d0 RDI: 0000000000000007 * lack of information about struct members: @@ -23937,666 +22908,538 @@ crash> task PID: 11077 TASK: ffff88005fd59fa0 CPU: 1 COMMAND: "bash" struct task_struct { - state = 0, - stack = 0xffff880062ab0000, + state = 0, + stack = , <<-- usage = { counter = 2 ... vtime_seqlock = { seqcount = { sequence = 0 - }, + }, lock = { - { - rlock = { - raw_lock = { - val = { - counter = 0 - } - } - } - } + {...} <<-- Can we unshorten this abbreviation?
