gdbstub: Replace strcpy() by strscpy()

2019-05-02T12:40:27Z

The strcpy() function is being deprecated. Replace it by the safer strscpy() and fix the following Coverity warning: "You might overrun the 1024-character fixed-size string remcom_in_buffer by copying cmd without checking the length."

gdbstub: mark expected switch fall-throughs

2019-05-02T12:38:04Z

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warnings: kernel/debug/gdbstub.c: In function ‘gdb_serial_stub’: kernel/debug/gdbstub.c:1031:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (remcom_in_buffer[1] == '\0') { ^ kernel/debug/gdbstub.c:1036:3: note: here case 'C': /* Exception passing */ ^~~~ kernel/debug/gdbstub.c:1040:7: warning: this statement may fall through [-Wimplicit-fallthrough=] if (tmp == 0) ^ kernel/debug/gdbstub.c:1043:3: note: here case 'c': /* Continue packet */ ^~~~ kernel/debug/gdbstub.c:1050:4: warning: this statement may fall through [-Wimplicit-fallthrough=] dbg_activate_sw_breakpoints(); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ kernel/debug/gdbstub.c:1052:3: note: here default: ^~~~~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 Notice that, in this particular case, the code comment is modified in accordance with what GCC is expecting to find. This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough. Signed-off-by: Gustavo A. R. Silva Acked-by: Jason Wessel Signed-off-by: Daniel Thompson

sched/headers: Prepare for new header dependencies before moving code to

2017-03-02T07:42:29Z

We are going to split out of , which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder file that just maps to to make this patch obviously correct and bisectable. Include the new header in the files that are going to need it.

If people aren't using it we shouldn't be carrying it. :-) Cleanups: - Remove kdb ssb command - there is no in kernel disassembler to support it - Remove kdb ll command - Always caused a kernel oops and there were no bug reports so no one was using this command - Use kernel ARRAY_SIZE macro instead of array computations Fixes: - Stop oops in kdb if user executes kdb_defcmd with args - kdb help command truncated text - ppc64 support for kgdbts - Add missing kconfig option from original kdb port for dealing with catastrophic kernel crashes such that you can reboot automatically on continue from kdb" * tag 'for_linux-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/jwessel/kgdb: kdb: Remove unhandled ssb command kdb: Prevent kernel oops with kdb_defcmd kdb: Remove the ll command kdb_main: fix help print kdb: Fix overlap in buffers with strcpy Fixed dead ifdef block by adding missing Kconfig option. kdb: Setup basic kdb state before invoking commands via kgdb kdb: use ARRAY_SIZE where possible kgdb/kgdbts: support ppc64 kdb: A fix for kdb command table expansion

kdb: Setup basic kdb state before invoking commands via kgdb

2013-03-02T14:52:17Z

Although invasive kdb commands are not supported via kgdb, some useful non-invasive commands like bt* require basic kdb state to be setup before calling into the kdb code. Factor out some of this code and call it before and after executing kdb commands via kgdb. Signed-off-by: Matt Klein Signed-off-by: Jason Wessel

kgdb: remove #include from kgdb.h

2013-02-04T23:35:26Z

There's no reason kgdb.h itself needs to include the 8250 serial port header file. So push it down to the _very_ limited number of individual drivers that need the values in that file, and fix up the places where people really wanted serial_core.h and platform_device.h.

kgdb,debug-core,gdbstub: Hook the reboot notifier for debugger detach

2012-03-22T20:07:15Z

The gdbstub and kdb should get detached if the system is rebooting. Calling gdbstub_exit() will set the proper debug core state and send a message to any debugger that is connected to correctly detach. An attached debugger will receive the exit code from include/linux/reboot.h based on SYS_HALT, SYS_REBOOT, etc... Reported-by: Jan Kiszka Signed-off-by: Jason Wessel

kdb,kgdb: Implement switch and pass buffer from kdb -> gdb

2011-08-01T18:23:59Z

When switching from kdb mode to kgdb mode packets were getting lost depending on the size of the fifo queue of the serial chip. When gdb initially connects if it is in kdb mode it should entirely send any character buffer over to the gdbstub when switching connections. Previously kdb was zero'ing out the character buffer and this could lead to gdb failing to connect at all, or a lengthy pause could occur on the initial connect. Signed-off-by: Jason Wessel
