rpmsg: Correct support for MODULE_DEVICE_TABLE()

2018-11-20T18:04:55+00:00

commit 5b7d127726de6eed4b900bc3bbb167837690818f upstream. Due to missing a missing entry in file2alias.c MODULE_DEVICE_TABLE() are not generating the proper module aliases. Add the needed entry here.

module/retpoline: Warn about missing retpoline in module

2018-03-19T18:59:11+00:00

commit caf7501a1b4ec964190f31f9c3f163de252273b8 upstream. There's a risk that a kernel which has full retpoline mitigations becomes vulnerable when a module gets loaded that hasn't been compiled with the right compiler or the right option. To enable detection of that mismatch at module load time, add a module info string "retpoline" at build time when the module was compiled with retpoline support. This only covers compiled C source, but assembler source or prebuilt object files are not checked. If a retpoline enabled kernel detects a non retpoline protected module at load time, print a warning and report it in the sysfs vulnerability file.

modpost: don't emit section mismatch warnings for compiler optimizations

2017-11-11T13:33:42+00:00

commit 4a3893d069b788f3570c19c12d9e986e8e15870f upstream. Currently an allyesconfig build [gcc-4.9.1] can generate the following: WARNING: vmlinux.o(.text.unlikely+0x3864): Section mismatch in reference from the function cpumask_empty.constprop.3() to the variable .init.data:nmi_ipi_mask which comes from the cpumask_empty usage in arch/x86/kernel/nmi_selftest.c. Normally we would not see a symbol entry for cpumask_empty since it is: static inline bool cpumask_empty(const struct cpumask *srcp) however in this case, the variant of the symbol gets emitted when GCC does constant propagation optimization. Fix things up so that any locally optimized constprop variants don't warn when accessing variables that live in the __init sections.

modpost: expand pattern matching to support substring matches

2017-11-11T13:33:42+00:00

commit 09c20c032b0f753969ae778d9783d946f054d7fe upstream. Currently the match() function supports a leading * to match any prefix and a trailing * to match any suffix. However there currently is not a combination of both that can be used to target matches of whole families of functions that share a common substring. Here we expand the *foo and foo* match to also support *foo* with the goal of targeting compiler generated symbol names that contain strings like ".constprop." and ".isra."

of: fix autoloading due to broken modalias with no 'compatible'

2016-08-22T21:38:10+00:00

commit b3c0a4dab7e35a9b6d69c0415641d2280fdefb2b upstream. Because of an improper dereference, a stray 'C' character was output to the modalias when no 'compatible' was specified. This is the case for some old PowerMac drivers which only set the 'name' property. Fix it to let them match again.
