Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

kbuild: check for section mismatch during modpost stage Section mismatch is identified as references to .init* sections from non .init sections. And likewise references to .exit.* sections outside .exit sections. .init.* sections are discarded after a module is initialized and references to .init.* sections are oops candidates. .exit.* sections are discarded when a module is built-in and thus references to .exit are also oops candidates. The checks were possible to do using 'make buildcheck' which called the two perl scripts: reference_discarded.pl and reference_init.pl. This patch just moves the same functionality inside modpost and the scripts are then obsoleted. They will though be kept for a while so users can do double checks - but note that some .o files are skipped by the perl scripts so result is not 1:1. All credit for the concept goes to Keith Owens who implemented the original perl scrips - this patch just moves it to modpost. Compared to the perl script the implmentation in modpost will be run for each kernel build - thus catching the error much sooner, but the downside is that the individual .o file are not always identified.

kbuild: try harder to find symbol names in modpost The relocation record sometimes contained an address which was not an exactly match for a symbol. Implment some simple logic such that if there is a symbol within 20 bytes of the address contained in the relocation record then print the name of this symbol. With this change modpost could find symbol names for the remaining .init.text symbols in my allyesconfig build for x86_64. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

[PATCH] kbuild: check SHT_REL sections I found that modpost can not detect section mismatch on mips and i386. On mips64, the modpost (with r_info layout fix) can detect it. The current modpst only checks SHT_RELA section but I suppose SHT_REL section should be checked also. This patch does not contain r_info layout fix. I'll post an updated r_info layout fix on next mail. Check SHT_REL sections as like as SHT_RELA sections to detect section mismatch.

kbuild: check license compatibility when building modules Modules that uses GPL symbols can no longer be build with kbuild, the build will fail during the modpost step. When a GPL-incompatible module uses a EXPORT_SYMBOL_GPL_FUTURE symbol then warn during modpost so author are actually notified. The actual license compatibility check is shared with the kernel to make sure it is in sync.

Linux Kernel Markers: create modpost file This adds some new magic in the MODPOST phase for CONFIG_MARKERS. Analogous to the Module.symvers file, the build will now write a Module.markers file when CONFIG_MARKERS=y is set. This file lists the name, defining module, and format string of each marker, separated by \t characters. This simple text file can be used by offline build procedures for instrumentation code, analogous to how System.map and Module.symvers can be useful to have for kernels other than the one you are running right now. The strings are made easy to extract by having the __trace_mark macro define the name and format together in a single array called __mstrtab_* in the __markers_strings section. This is straightforward and reliable as long as the marker structs are always defined by this macro. It is an unreasonable amount of hairy work to extract the string pointers from the __markers section structs, which entails handling a relocation type for every machine under the sun.
