lib/decompressors: use real out buf size for gunzip with kernel

2015-09-10T20:29:01+00:00

When loading x86 64bit kernel above 4GiB with patched grub2, got kernel gunzip error. | early console in decompress_kernel | decompress_kernel: | input: [0x807f2143b4-0x807ff61aee] | output: [0x807cc00000-0x807f3ea29b] 0x027ea29c: output_len | boot via startup_64 | KASLR using RDTSC... | new output: [0x46fe000000-0x470138cfff] 0x0338d000: output_run_size | decompress: [0x46fe000000-0x47007ea29b] <=== [0x807f2143b4-0x807ff61aee] | | Decompressing Linux... gz... | | uncompression error | | -- System halted the new buffer is at 0x46fe000000ULL, decompressor_gzip is using 0xffffffb901ffffff as out_len. gunzip in lib/zlib_inflate/inflate.c cap that len to 0x01ffffff and decompress fails later. We could hit this problem with crashkernel booting that uses kexec loading kernel above 4GiB. We have decompress_* support: 1. inbuf[]/outbuf[] for kernel preboot. 2. inbuf[]/flush() for initramfs 3. fill()/flush() for initrd. This bug only affect kernel preboot path that use outbuf[]. Add __decompress and take real out_buf_len for gunzip instead of guessing wrong buf size.

ARM: 8373/1: disable branch profiling in uncompressor

2015-05-27T23:29:14+00:00

The branch profiling code cannot work outside of the main kernel and just causes link errors if we try to use it in the decompressor. Disabling it here matches what we do for other architectures. Signed-off-by: Arnd Bergmann Signed-off-by: Russell King

ARM: replace BSYM() with badr assembly macro

2015-05-08T16:33:50+00:00

BSYM() was invented to allow us to work around a problem with the assembler, where local symbols resolved by the assembler for the 'adr' instruction did not take account of their ISA. Since we don't want BSYM() used elsewhere, replace BSYM() with a new macro 'badr', which is like the 'adr' pseudo-op, but with the BSYM() mechanics integrated into it. This ensures that the BSYM()-ification is only used in conjunction with 'adr'. Acked-by: Dave Martin Acked-by: Nicolas Pitre Signed-off-by: Russell King
