When no interfaces are returned by the server we cannot open multiple
channels. Make it more obvious by reporting that to the user at the
VFS log level.

RHBZ: 1795423
This is the SMB1 version of a patch we already have for SMB2
In recent DFS updates we have a new variable controlling how many times we will
retry to reconnect the share.
If DFS is not used, then this variable is initialized to 0 in:
static inline int
dfs_cache_get_nr_tgts(const struct dfs_cache_tgt_list *tl)
{
return tl ? tl->tl_numtgts : 0;
}
This means that in the reconnect loop in smb2_reconnect() we will immediately wrap retries to -1
and never actually get to pass this conditional:
if (--retries)
continue;
The effect is that we no longer reach the point where we fail the commands with -EHOSTDOWN
and basically the kernel threads are virtually hung and unkillable.

Brown paperbag time: fetching ->i_uid/->i_mode really should've been
done from nd->inode. I even suggested that, but the reason for that has
slipped through the cracks and I went for dir->d_inode instead - made
for more "obvious" patch.
Analysis:
- at the entry into do_last() and all the way to step_into(): dir (aka
nd->path.dentry) is known not to have been freed; so's nd->inode and
it's equal to dir->d_inode unless we are already doomed to -ECHILD.
inode of the file to get opened is not known.
- after step_into(): inode of the file to get opened is known; dir
might be pointing to freed memory/be negative/etc.
- at the call of may_create_in_sticky(): guaranteed to be out of RCU
mode; inode of the file to get opened is known and pinned; dir might
be garbage.
The last was the reason for the original patch. Except that at the
do_last() entry we can be in RCU mode and it is possible that
nd->path.dentry->d_inode has already changed under us.
In that case we are going to fail with -ECHILD, but we need to be
careful; nd->inode is pointing to valid struct inode and it's the same
as nd->path.dentry->d_inode in "won't fail with -ECHILD" case, so we
should use that.

When we generate the help text of a symbol (e.g. when a user presses '?'
in menuconfig), we do two things:
1. We iterate through every prompt that belongs to that symbol,
printing its text and its location in the menu tree.
2. We print symbol-wide information that's not linked to a particular
prompt, such as what it selects/is selected by and what it
implies/is implied by.
Each prompt we print for 1 starts with a line that's not indented
indicating where the prompt is defined, then continues with indented
lines that describe properties of that particular definition.
Once we get to 2, however, we print all the global data indented as
well! Visually, this makes it look like the symbol-wide data is
associated with the last prompt we happened to print rather than
the symbol as a whole.
Fix this by removing the indentation for symbol-wide information.

Kconfig makes a distinction between dependencies (defined by "depends
on" expressions and enclosing "if" blocks) and visibility (which
includes all dependencies, but also includes inline "if" expressions of
individual properties as well as, for prompts, "visible if" expressions
of enclosing menus).
Before commit bcdedcc1afd6 ("menuconfig: print more info for symbol
without prompts"), the "Depends on" lines of a symbol's help text
indicated the visibility of the prompt property they appeared under.
After bcdedcc1afd, there was always only a single "Depends on" line,
which indicated the visibility of the first P_SYMBOL property of the
symbol. Since P_SYMBOLs never have inline if expressions, this was in
effect the same as the dependencies of the menu item that the P_SYMBOL
was attached to.
Neither of these situations accurately conveyed the dependencies of a
symbol--the first because it was actually the visibility, and the second
because it only showed the dependencies from a single definition.
With this series, we are back to printing separate dependencies for each
definition, but we print the actual dependencies (rather than the
visibility) in the "Depends on" line. However, it can still be useful to
know the visibility of a prompt, so this patch adds a "Visible if" line
that shows the visibility only if the visibility is different from the
dependencies (which it isn't for most prompts in Linux).

In Kconfig, each symbol (representing a config option) can be defined in
multiple places. Each definition may or may not have a prompt, which
allows the option to be set via an interface like menuconfig. Each
definition has a set of dependencies, which determine whether its prompt
is visible and whether other pieces of the definition, like a default
value, take effect.
Historically, a symbol's help text (i.e. what's shown when a user
presses '?' in menuconfig) contained some symbol-wide information not
tied to any particular definition (e.g. what other symbols it selects)
as well as the location (file name and line number) and dependencies of
each prompt. Notably, the help text did not show the location or
dependencies of definitions without prompts.
Because this made it hard to reason about symbols that had no prompts,
commit bcdedcc1afd6 ("menuconfig: print more info for symbol without
prompts") changed the help text so that, instead of containing the
location and dependencies of each prompt, it contained the location and
dependencies of the symbol's first definition, regardless of whether or
not that definition had a prompt.
For symbols with only one definition, that change makes sense. However,
it breaks down for symbols with multiple definitions: each definition
has its own set of dependencies (the `dep` field of `struct menu`), and
those dependencies are ORed together to get the symbol's dependency list
(the `dir_dep` field of `struct symbol`). By printing only the
dependencies of the first definition, the help text misleads users into
believing that an option is more narrowly-applicable than it actually
is.
For an extreme example of this, we can look at the SYS_TEXT_BASE symbol
in the Das U-Boot project (version 2019.10), which also uses Kconfig. (I
unfortunately could not find an illustrative example in Linux.) This
config option specifies the load address of the built binary and, as
such, is applicable to basically every configuration possible. And yet,
without this patch, its help text is as follows:
Symbol: SYS_TEXT_BASE [=]
Type : hex
Prompt: U-Boot base address
Location:
-> ARM architecture
Prompt: Text Base
Location:
-> Boot images
Defined at arch/arm/mach-aspeed/Kconfig:9
Depends on: ARM [=n] && ARCH_ASPEED [=n]
The help text indicates that the option is applicable only for a
specific unselected architecture (aspeed), because that architecture's
promptless definition (which just sets a default value), happens to be
the first one seen. No definition or dependency information is printed
for either of the two prompts listed.
Because source locations and dependencies are fundamentally properties
of definitions and not of symbols, we should treat them as such. This
patch brings back the pre-bcdedcc1afd6 behavior for definitions with
prompts but also separately prints the location and dependencies of
those without prompts, solving the original problem in a different way.
With this change, our SYS_TEXT_BASE example becomes
Symbol: SYS_TEXT_BASE [=]
Type : hex
Defined at arch/arm/mach-stm32mp/Kconfig:83
Prompt: U-Boot base address
Depends on: ARM [=n] && ARCH_STM32MP [=n]
Location:
-> ARM architecture
Defined at Kconfig:532
Prompt: Text Base
Depends on: !NIOS2 [=n] && !XTENSA [=n] && !EFI_APP [=n]
Location:
-> Boot images
Defined at arch/arm/mach-aspeed/Kconfig:9
Depends on: ARM [=n] && ARCH_ASPEED [=n]
Defined at arch/arm/mach-socfpga/Kconfig:25
Depends on: ARM [=n] && ARCH_SOCFPGA [=n]
<snip>
Defined at board/sifive/fu540/Kconfig:15
Depends on: RISCV [=n] && TARGET_SIFIVE_FU540 [=n]
which is a much more accurate representation.
Note that there is one notable difference between what gets printed for
prompts after this change and what got printed before bcdedcc1afd6: the
"Depends on" line now accurately represents the prompt's dependencies
instead of conflating those with the prompt's visibility (which can
include extra conditions). See the patch later in this series titled
"kconfig: distinguish between dependencies and visibility in help text"
for more details and better handling of that nuance.

Since kernel configs provided by syzbot are close to "make allyesconfig",
it takes long time to rebuild. This is especially waste of time when we
need to rebuild for many times (e.g. doing manual printk() inspection,
bisect operations).
We can save time if we can exclude modules which are irrelevant to each
problem. But "make localmodconfig" cannot exclude modules which are built
into vmlinux because /sbin/lsmod output is used as the source of modules.
Therefore, this patch adds "make yes2modconfig" which converts from =y
to =m if possible. After confirming that the interested problem is still
reproducible, we can try "make localmodconfig" (and/or manually tune
based on "Modules linked in:" line) in order to exclude modules which are
irrelevant to the interested problem. While we are at it, this patch also
adds "make mod2yesconfig" which converts from =m to =y in case someone
wants to convert from =m to =y after "make localmodconfig".

Commit 8636a1f9677d ("treewide: surround Kconfig file paths with double
quotes") killed use-cases to reduce an unquoted string into the 'prompt'
symbol.
Kconfig still allows to use an unquoted string in the context of menu,
source, or prompt.
So, you can omit quoting if the prompt is a single word:
bool foo
..., but I do not think this is so useful.
Let's require quoting:
bool "foo"
All the Kconfig files in the kernel are written in this way.
Remove the T_WORD from the right-hand side of the symbol 'prompt'.

In menu_finalize(), the dependency of a menu entry is propagated
downwards.
For the 'menu', parent->dep and parent->prompt->visible.expr have
the same expression. Both accumulate the 'depends on' of itself and
upper menu entries.

This reverts commit ba6ff60d5eb4 ("kconfig: don't emit warning upon
rootmenu's prompt redefinition").
At that time, rootmenu.prompt was always set first, then it was set
again if a "mainmenu" statement was specified in the Kconfig file.
This is no longer the case since commit 0724a7c32a54 ("kconfig: Don't
leak main menus during parsing"). Remove the unneeded check.

The temporary directory names, debian/hdrtmp (linux-headers package)
vs debian/headertmp (linux-libc-dev package), are confusing.
Matching the directory name to the package name is clearer, IMHO.

- We do not need tools/objtool/fixdep or tools/objtool/sync-check.sh
for building external modules. Including tools/objtool/objtool is
enough.
- gcc-common.h is a check-in file. I do not see any point to search
for it in objtree.

Currently, -E (stop after the preprocessing stage) is used to check
whether the given compiler flag is supported.
While it is faster than -S (or -c), it can be false-positive. You need
to run the compilation proper to check the flag more precisely.
For example, -E and -S disagree about the support of
"--param asan-instrument-allocas=1".
$ gcc -Werror --param asan-instrument-allocas=1 -E -x c /dev/null -o /dev/null
$ echo $?
0
$ gcc -Werror --param asan-instrument-allocas=1 -S -x c /dev/null -o /dev/null
cc1: error: invalid --param name ‘asan-instrument-allocas’; did you mean ‘asan-instrument-writes’?
$ echo $?
1

Bartosz Golaszewski reports that when "make {menu,n,g,x}config" fails
due to missing packages, a temporary file is left over, which is not
ignored by git.
For example, if GTK+ is not installed:
$ make gconfig
*
* Unable to find the GTK+ installation. Please make sure that
* the GTK+ 2.0 development package is correctly installed.
* You need gtk+-2.0 gmodule-2.0 libglade-2.0

scripts/kconfig/Makefile:208: recipe for target 'scripts/kconfig/gconf-cfg' failed
make[1]: *** [scripts/kconfig/gconf-cfg] Error 1
Makefile:567: recipe for target 'gconfig' failed
make: *** [gconfig] Error 2
$ git status
HEAD detached at v5.4
Untracked files:
(use "git add <file>..." to include in what will be committed)
scripts/kconfig/gconf-cfg.tmp
nothing added to commit but untracked files present (use "git add" to track)
This is because the check scripts are run with filechk, which misses
to clean up the temporary file on failure.
When the line
{ $(filechk_$(1)); } > $@.tmp;
... fails, it exits immediately due to the 'set -e'. Use trap to make
sure to delete the temporary file on exit.
For extra safety, I replaced $@.tmp with $(dot-target).tmp to make it
a hidden file.

Currently, usr/gen_initramfs.sh takes care of all the use-cases:
[1] generates a cpio file unless CONFIG_INITRAMFS_SOURCE points to
a single cpio archive
[2] If CONFIG_INITRAMFS_SOURCE is the path to a cpio archive,
use it as-is.
[3] Compress the cpio file according to CONFIG_INITRAMFS_COMPRESSION_*
unless it is passed a compressed archive.
To simplify the script, move [2] and [3] to usr/Makefile.
If CONFIG_INITRAMFS_SOURCE is the path to a cpio archive, there is
no need to run this shell script.
For the cpio archive compression, you can re-use the rules from
scripts/Makefile.lib .

When CONFIG_INITRAMFS_SOURCE is empty, the Makefile passes the -d
option to gen_initramfs.sh to create the default initramfs, which
contains /dev, /dev/console, and /root.
This commit simplifies the default behavior; remove the -d option,
and add the default cpio list.

Currently, this script is run twice, for the dependency list, and then
for the cpio archive.
The first one is re-run every time although its build log is suppressed
so nobody notices it.
Make it work more efficiently by generating the cpio and the dependency
list at the same time.
