2018-08-22kbuild: make sorting initramfs contents independent of localeAndrzej Pietrasiewicz
Some LANG values (e.g. pl_PL.UTF-8) cause the sort command to output files before their parent directories, which makes them inaccessible for the kernel. In other words, when the kernel populates the rootfs, it is unable to create files whose parent directories have not been yet created. This patch makes sorting use the default (LANG=C) locale, which results in correctly laid out initramfs images (parent directories before files).

2018-08-22kbuild: Add a space after `!` to prevent parsing as file patternMichael Forney
Some shells use !(pattern|...|pattern) to match file names not containing the specified patterns.

POSIX says[0] If the pipeline begins with the reserved word ! and command1 is a subshell command, the application shall ensure that the ( operator at the beginning of command1 is separated from the ! by one or more <blank> characters. The behavior of the reserved word ! immediately followed by the ( operator is unspecified. So, just add a <blank> to prevent this.

2018-08-22kconfig: improve the recursive dependency reportMasahiro Yamada
This commit improves the messages of the recursive dependency. Currently, sym->dir_dep.expr is not checked. Hence, any dependency in property visibility is regarded as the dependency of the symbol. [Test Code 1] config A bool "a" depends on B config B bool "b" depends on A [Test Code 2] config A bool "a" if B config B bool "b" depends on A For both cases above, the same message is displayed: symbol B depends on A symbol A depends on B This commit changes the message for the latter, like this: symbol B depends on A symbol A prompt is visible depending on B Also, 'select' and 'imply' are distinguished.

2018-08-22kconfig: report recursive dependency involving 'imply'Masahiro Yamada
Currently, Kconfig does not complain about the recursive dependency where 'imply' keywords are involved. [Test Code] config A bool "a" config B bool "b" imply A depends on A In the code above, Kconfig cannot calculate the symbol values correctly due to the circular dependency. For example, allyesconfig followed by syncconfig results in an odd behavior because CONFIG_B becomes visible in syncconfig. $ make allyesconfig scripts/kconfig/conf --allyesconfig Kconfig # # configuration written to .config # $ cat .config # # Automatically generated file; DO NOT EDIT. # Main menu # CONFIG_A=y $ make syncconfig scripts/kconfig/conf --syncconfig Kconfig * * Restart config... * * * Main menu * a (A) [Y/n/?] y b (B) [N/y/?] (NEW) To detect this correctly, sym_check_expr_deps() should recurse to not only sym->rev_dep.expr but also sym->implied.expr . At this moment, sym_check_print_recursive() cannot distinguish 'select' and 'imply' since it does not know the precise context where the recursive dependency has been hit. This will be solved by the next commit. In fact, even the document and the unit-test are confused. Using 'imply' does not solve recursive dependency since 'imply' addresses the unmet direct dependency, which 'select' could cause.

2018-08-22kconfig: error out when seeing recursive dependencyMasahiro Yamada
Originally, recursive dependency was a fatal error for Kconfig because Kconfig cannot compute symbol values in such a situation. Commit d595cea62403 ("kconfig: print more info when we see a recursive dependency") changed it to a warning, which I guess was not intentional. Get it back to an error again. Also, rename the unit test directory "warn_recursive_dep" to "err_recursive_dep" so that it matches to the behavior.

2018-08-22scripts/dtc: consolidate include path options in MakefileMasahiro Yamada
It is tedious to specify extra compiler options for every file. HOST_EXTRACFLAGS is useful to add options to all files in a directory. -I$(src)/libfdt is needed for all the files in this directory to include libfdt_env.h etc. from scripts/dtc/libfdt/. On the other hand, -I$(src) is used to include check-in headers from generated C files. Thus, I added it only to dtc-lexer.lex.o and dtc-parser.tab.o .

2018-08-22y2038: Provide aliases for compat helpersArnd Bergmann
As part of the system call rework for 64-bit time_t, we are restructuring the way that compat syscalls deal with 32-bit time_t, reusing the implementation for 32-bit architectures. Christoph Hellwig suggested a rename of the associated types and interfaces to avoid the confusing usage of the 'compat' prefix for 32-bit architectures. To prepare for doing that in linux-4.20, add a set of macros that allows to convert subsystems separately to the new names and avoids some of the nastier merge conflicts.

2018-08-22h8300:let the checker know that size_t is ulongLuc Van Oostenryck
All 64bit archs use unsigned long for size_t and most 32bit archs use 'unsigned int'. By default, this is what is assumed by sparse. However, on h8300 (a 32bit arch) size_t is unsigned long which can led sparse to emit wrong warnings. Fix this by passing to sparse the flag -msize-long, telling it that size_t is unsigned long.

2018-08-21iscsi target: fix session creation failure handlingMike Christie
The problem is that iscsi_login_zero_tsih_s1 sets conn->sess early in iscsi_login_set_conn_values.

This patch has iscsi_login_zero_tsih_s1 either completely setup the session or completely tear it down, so later in iscsi_target_login_sess_out we can just check for it being set to the connection.
