scripts/checkstack.pl: automatically handle 32-bit and 64-bit mode for ARCH=x86

2014-08-08T22:57:27Z

This patch adds support for ARCH=x86 into checkstack. Commit ffee0de411fd ("x86: Default to ARCH=x86 to avoid overriding CONFIG_64BIT") had merged ARCH=i386 and ARCH=x86_64 into one ARCH=x86. checkstack.pl searches patterns of machine instructions which are usually used for allocating stack frames. checkstalk.pl needs either i386 or x86_64, x86 isn't enough: $ make checkstack objdump -d vmlinux $(find . -name '*.ko') | \ perl linux/scripts/checkstack.pl x86 wrong or unknown architecture "x86" Signed-off-by: Konstantin Khlebnikov Cc: David Woodhouse Cc: "H.

scripts: improve checkstack

2010-03-07T20:19:09Z

Cleanup checkstack script: * Turn on strict checking * Fix resulting error message because the declaration syntax was incorrect. * Remove incorrect and misleading use of prototype - prototype not required for this type of sort function because $a and $b are being used in this contex - if prototype was being used it should be for both arguments * Use closure for sort function Signed-off-by: Stephen Hemminger Cc: Steven Rostedt Cc: Arjan van de Ven Cc: Cong Wang Cc: Michal Marek Signed-off-by: Andrew Morton Signed-off-by: Michal Marek

[S390] Fix checkstack for s390

2008-10-10T19:34:03Z

With -march=z990 and later gcc can use the long displacement facility insruction lay for stack register handling. This patch adopts checkstack to catch lay in addition to ahi and aghi. Signed-off-by: Christian Borntraeger Signed-off-by: Martin Schwidefsky

fix checkstack.pl arch detection

2008-07-25T17:53:27Z

uname -m was leaving a newline in $arch, and not passing the tests. Also, printing the unknown arch on failure is probably helpful. Signed-off-by: Eric Sandeen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

find dynamic stack allocations in checkstack.pl

2008-07-25T17:53:26Z

Currently, checkstack.pl only looks for fixed subtractions from the stack pointer. However, things like this: void function(int size) { char stackbuster[size << 2]; ... are certainly worth pointing out, I think. This could perhaps be done more cleanly, and the following patch only adds "dynamic" REs for x86 and x86_64, but it works: 0x00b0 crypto_cbc_decrypt_inplace [cbc]: Dynamic (%rax) 0x00ad crypto_pcbc_decrypt_inplace [pcbc]: Dynamic (%rax) 0x02f6 crypto_pcbc_encrypt_inplace [pcbc]: Dynamic (%rax) 0x036c _crypto_xcbc_digest_setkey [xcbc]: Dynamic (%rax) ...

Claim maintainership for block2mtd and update email addresses

2008-02-06T18:41:09Z

I have been prime author and maintainer of block2mtd from day one, but neither MAINTAINERS nor the module source makes this fact clear. And while I'm at it, update my email addresses tree-wide, as the old address currently bounces and change my name to "joern" as unicode will likely continue to cause trouble until the end of this century.
