This installs a silent breakpoint on the do_init_module function. The breakpoint handler will try to load symbols from the module files found during lx-symbols execution. This way, breakpoints can be set to module initialization functions, and there is no need to explicitly call lx-symbols after (re-)loading a module. Signed-off-by:

This is probably the most useful helper when debugging kernel modules: lx-symbols first reloads vmlinux. Then it searches recursively for *.ko files in the specified paths and the current directory. Finally it walks the kernel's module list, issuing the necessary add-symbol-file command for each loaded module so that gdb knows which module symbol corresponds to which address. It also looks up variable sections (bss, data, rodata) and appends their address to the add-symbole-file command line. This allows to access global module variables just like any other variable.

Provide an internal helper with container_of semantics. As type lookups are very slow in gdb-python and we need a type "long" for this, cache the reference to this type object. Then export the helper also as a convenience function form use at the gdb command line. Signed-off-by:

Type lookups are very slow in gdb-python which is often noticeable when iterating over a number of objects. Introduce the helper class CachedType that keeps a reference to a gdb.Type object but also refreshes it after an object file has been loaded. Signed-off-by:

This provides the basic infrastructure to load kernel-specific python helper scripts when debugging the kernel in gdb. The loading mechanism is based on gdb loading for <objfile>-gdb.py when opening <objfile>. Therefore, this places a corresponding link to the main helper script into the output directory that contains vmlinux. The main scripts will pull in submodules containing Linux specific gdb commands and functions. To avoid polluting the source directory with compiled python modules, we link to them from the object directory. Due to gdb.parse_and_eval and string redirection for gdb.execute, we depend on gdb >= 7.2. This feature is enabled via CONFIG_GDB_SCRIPTS. Signed-off-by:

The spinlock in eventfd_poll is trying to protect the count of events so it can decide if it should return POLLIN, POLLERR, or POLLOUT. But, because of the way we drop the lock after calling poll_wait, and drop it again before returning, we have the same pile of races with the lock as we do with a single read of ctx->count(). This replaces the lock with a read barrier and single read. eventfd_write does a single bump of ctx->count, so this should not add new races with adding events. eventfd_read is similar, it will do a single decrement with the lock held, and so we're making the race with concurrent readers slightly larger. This spinlock is the top CPU user in kernel code during one of our workloads. Removing it gives us a ~2% boost.

When updating PT_NOTE header size (ie. p_memsz), an overflow issue happens with the following bogus note entry: n_namesz = 0xFFFFFFFF n_descsz = 0x0 n_type = 0x0 This kind of note entry should be dropped during updating p_memsz. But because n_namesz is 32bit, after (n_namesz + 3) & (~3), it's overflow to 0x0, the note entry size looks sane and reserved. When userspace (eg. crash utility) is trying to access such bogus note, it could lead to an unexpected behavior (eg. crash utility segment fault because it's reading bogus address). The source of bogus note hasn't been identified yet. At least we could drop the bogus note so user space wouldn't be surprised. Signed-off-by:

Add a new kexec preprocessor macro IND_FLAGS, which is the bitwise OR of all the possible kexec IND_ kimage_entry indirection flags. Having this macro allows for simplified code in the prosessing of the kexec kimage_entry items. Also, remove the local powerpc definition and use the generic one. Signed-off-by:

Geoff Levand authored
Define new kexec preprocessor macros IND_*_BIT that define the bit position of the kimage entry flags. Change the existing IND_* flag macros to be defined as bit shifts of the corresponding IND_*_BIT macros. Also wrap all C language code in kexec.h with #if !defined(__ASSEMBLY__) so assembly files can include kexec.h to get the IND_* and IND_*_BIT macros. Some CPU instruction sets have tests for bit position which are convenient in implementing routines that operate on the kimage entry list. The addition of these bit position macros in a common location will avoid duplicate definitions and the chance that changes to the IND_* flags will not be propagated to assembly files. Signed-off-by:

Simplify the code around one of the conditionals in the kexec_load syscall routine. The original code was confusing with a redundant check on KEXEC_ON_CRASH and comments outside of the conditional block. This change switches the order of the conditional check, and cleans up the comments for the conditional. There is no functional change to the code. Signed-off-by:

Remove the unneded declaration for a kexec_load() routine.

struct kimage has a member destination which is used to store the real destination address of each page when load segment from user space buffer to kernel. But we never retrieve the value stored in kimage->destination, so this member variable in kimage and its assignment operation are redundent code. I guess for_each_kimage_entry just does the work that kimage->destination is expected to do. So in this patch just make a cleanup to remove it. Signed-off-by:
