hw/arm: Replace fprintf(stderr, "*\n" with error_report() Replace a large number of the fprintf(stderr, "*\n" calls with error_report(). The functions were renamed with these commands and then compiler issues where manually fixed. find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N;N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + find ./* -type f -exec sed -i \ 'N; {s|fprintf(stderr, "\(.*\)\\n"\(.*\));|error_report("\1"\2);|Ig}' \ {} + Some lines where then manually tweaked to pass checkpatch.

Fix bad error handling after memory_region_init_ram() Symptom: $ qemu-system-x86_64 -m 10000000 Unexpected error in ram_block_add() at /work/armbru/qemu/exec.c:1456: upstream-qemu: cannot set up guest memory 'pc.ram': Cannot allocate memory Aborted (core dumped) Root cause: commit ef701d7 screwed up handling of out-of-memory conditions. Before the commit, we report the error and exit(1), in one place, ram_block_add(). The commit lifts the error handling up the call chain some, to three places. Fine. Except it uses &error_abort in these places, changing the behavior from exit(1) to abort(), and thus undoing the work of commit 3922825 "exec: Don't abort when we can't allocate guest memory". The three places are: * memory_region_init_ram() Commit 4994653 (right after commit ef701d7) lifted the error handling further, through memory_region_init_ram(), multiplying the incorrect use of &error_abort. Later on, imitation of existing (bad) code may have created more. * memory_region_init_ram_ptr() The &error_abort is still there. * memory_region_init_rom_device() Doesn't need fixing, because commit 33e0eb5 (soon after commit ef701d7) lifted the error handling further, and in the process changed it from &error_abort to passing it up the call chain. Correct, because the callers are realize() methods. Fix the error handling after memory_region_init_ram() with a Coccinelle semantic patch: @r@ expression mr, owner, name, size, err; position p; @@ memory_region_init_ram(mr, owner, name, size, ( - &error_abort + &error_fatal | err@p ) ); @script:python@ p << r.p; @@ print "%s:%s:%s" % (p[0].file, p[0].line, p[0].column) When the last argument is &error_abort, it gets replaced by &error_fatal. This is the fix. If the last argument is anything else, its position is reported. This lets us check the fix is complete. Four positions get reported: * ram_backend_memory_alloc() Error is passed up the call chain, ultimately through user_creatable_complete(). As far as I can tell, it's callers all handle the error sanely. * fsl_imx25_realize(), fsl_imx31_realize(), dp8393x_realize() DeviceClass.realize() methods, errors handled sanely further up the call chain. We're good. Test case again behaves: $ qemu-system-x86_64 -m 10000000 qemu-system-x86_64: cannot set up guest memory 'pc.ram': Cannot allocate memory [Exit 1 ] The next commits will repair the rest of commit ef701d7's damage.
