kconfig/nconf: Fix hang when editing symbol with a long prompt

2017-01-26T16:39:15+00:00

commit 79e51b5c2deea542b3bb8c66e0d502230b017dde upstream.

Currently it is impossible to edit the value of a config symbol with a
prompt longer than (terminal width - 2) characters.  dialog_inputbox()
calculates a negative x-offset for the input window and newwin() fails
as this is invalid.  It also doesn't check for this failure, so it
busy-loops calling wgetch(NULL) which immediately returns -1.

The additions in the offset calculations also don't match the intended
size of the window.

Limit the window size and calculate the offset similarly to
show_scroll_win().

scripts/has-stack-protector: add -fno-PIE

2016-11-24T15:23:54+00:00

commit 82031ea29e454b574bc6f49a33683a693ca5d907 upstream.

Adding -no-PIE to the fstack protector check. -no-PIE was introduced
before -fstack-protector so there is no need for a runtime check.

Without it the build stops:
|Cannot use CONFIG_CC_STACKPROTECTOR_STRONG: -fstack-protector-strong available but compiler is broken

due to -mcmodel=kernel + -fPIE if -fPIE is enabled by default.

Tagging it stable so it is possible to compile recent stable kernels as
well.

CRIS: Fix headers_install

2016-10-06T06:22:00+00:00

commit 6eb64b8c64f7177b160b4bdbabd317d523bf4bfc upstream.

Fix headers_install by adjusting the path to arch files.
And delete unused Kbuild file.
Drop special handling of cris in the headers.sh script
as a nice side-effect.

ftrace/recordmcount: Work around for addition of metag magic but not relocations

2016-08-19T07:51:20+00:00

commit b2e1c26f0b62531636509fbcb6dab65617ed8331 upstream.

glibc recently did a sync up (94e73c95d9b5 "elf.h: Sync with the gabi
webpage") that added a #define for EM_METAG but did not add relocations

This triggers build errors:

scripts/recordmcount.c: In function 'do_file':
scripts/recordmcount.c:466:28: error: 'R_METAG_ADDR32' undeclared (first use in this function)
  case EM_METAG:  reltype = R_METAG_ADDR32;
                            ^~~~~~~~~~~~~~
scripts/recordmcount.c:466:28: note: each undeclared identifier is reported only once for each function it appears in
scripts/recordmcount.c:468:20: error: 'R_METAG_NONE' undeclared (first use in this function)
     rel_type_nop = R_METAG_NONE;
                    ^~~~~~~~~~~~

Work around this change with some more #ifdefery for the relocations.

kbuild/mkspec: fix grub2 installkernel issue

2016-04-11T14:44:24+00:00

commit c8b08ca558c0067bc9e15ce3f1e70af260410bb2 upstream.

mkspec is copying built kernel to temporrary location

	/boot/vmlinuz-$KERNELRELEASE-rpm

and runs installkernel on it. This however directly leads to grub2
menuentry for this suffixed binary being generated as well during the run
of installkernel script.

Later in the process the temporary -rpm suffixed files are removed, and
therefore we end up with spurious (and non-functional) grub2 menu entries
for each installed kernel RPM.

Fix that by using a different temporary name (prefixed by '.'), so that
the binary is not recognized as an actual kernel binary and no menuentry
is created for it.

genksyms: Handle string literals with spaces in reference files

2016-03-07T14:42:23+00:00

commit a78f70e8d65e88b9f631d073f68cb26dcd746298 upstream.

The reference files use spaces to separate tokens, however, we must
preserve spaces inside string literals. Currently the only case in the
tree is struct edac_raw_error_desc in :

$ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes
$ mv drivers/edac/amd64_edac.{symtypes,symref}
$ KBUILD_SYMTYPES=1 make -s drivers/edac/amd64_edac.symtypes

commit dd39a26538e37f6c6131e829a4a510787e43c783 upstream.

recordmcount edits the file in-place, which can cause problems when
using ccache in hardlink mode.  Arrange for recordmcount to break a
hardlinked object.

scripts/bloat-o-meter: fix python3 syntax error

2016-02-25T09:49:14+00:00

commit 72214a24a7677d4c7501eecc9517ed681b5f2db2 upstream.

In Python3+ print is a function so the old syntax is not correct
anymore:

  $ ./scripts/bloat-o-meter vmlinux.o vmlinux.o.old
    File "./scripts/bloat-o-meter", line 61
      print "add/remove: %s/%s grow/shrink: %s/%s up/down: %s/%s (%s)" % \
                                                                     ^
  SyntaxError: invalid syntax

Fix by calling print as a function.
