- mmap_seized returns only NULL on error, drop redumdant test - setup control block in one group - no need for err_free label, xfree handles NULL easily - prepare registers for munmap_seized call on error path Signed-off-by:

- err_restore_full label is redundant - must try to restore poked area if it's parially corrupted Signed-off-by:

It actually not a problem since we never reach a tail out of blob, but better to be on a safe side (after all there is no guarantee that .data section will not end up exactly at blob final bytes). Signed-off-by:

...and move tags/cscope removal to it. 'make clean' is traditionally used to remove all compiler-generated stuff in order to do a clean rebuild. 'make distclean' cleans more, it is used to prepare sources for 'make dist' (creating a source tarball). It is unfortunate to find out you have to run 'make tags cscope' every time after 'make clean'. Signed-off-by:

In the beginning it was the Word, and the Word was .space. Later, .skip was introduced as a synonym for .space, initially only for 680x0 platform. But the sole reason for this patch is that I use clang/llvm to check the code and unfortunately it does not understand .skip, printing long ugly warnings I'd like to avoid. Signed-off-by:

This name for the structure is obfuscating, because the structure will be used also for queues and semaphores sets migration. This patch renames this structure int ipc_desc_entry. It also renames all related functions and prints to reflect structure name change. Signed-off-by:

Since we now have the parasite memory shared with crtools process we can just memcpy this data between them. Signed-off-by:

Pavel Emelyanov authored
I don't like that we poke the parasite into remote space with 4k calls to ptrace. Now we have the /proc/pid/map_files/ dir which helps us sharing a mapping with some other process. Use this -- map the remote area for parasite locally and put the parasite blob into it with simple memcpy. Signed-off-by:

In fact all we need for parasitic syscall is -- original regs and some regs with syscall args to work on. The former one is obtained in the infect/cure code and the latter one is located (and copied from orig) nearby. That said, we can simplify all the regs passing-down code by removing intermediate instances and utilizing the top-level reg-s for this. Signed-off-by:

There's no need in 3 instances of regs in arguments. One is more than enough. Plus, this one can be made static. Signed-off-by:

Right now we do syscall_seized for this, but we have the misc dumping command and the core is (after patch #3) dump after parasite, so we can get brk from the misc dump, thus avoiding one more switch to parasite. Signed-off-by:
