The definition of COMPAT_LINUX_VERSION_CHECK_LT() macro lacks surrounding paretheses so that negated tests like !COMPAT_LINUX_VERSION_CHECK_LT(...) expand to something completely different. This could be worked around easily by adding parentheses to each place the macro is used in an expression but it makes much more sense to fix the macro definition so that the macro does not serve as a trap.
When building against kernel 4.12 and newer, macro name GDT_SIZE used in (vmmon) include/segs.h collides with macro defined in (kernel source) arch/x86/include/asm/segment.h, resulting in its redefinition. To prevent potential problems, rename vmmon's GDT_SIZE to VMMON_GDT_SIZE and GDT_LIMIT to VMMON_GDT_LIMIT. (There is no GDT_LIMIT in mainline kernel source but let's be consistent.)
The PCI_VENDOR_ID_VMWARE macro is defined in mainline pci_ids.h since
commit 94e57fea6202 ("PCI: Move PCI_VENDOR_ID_VMWARE to pci_ids.h") in
v3.18-rc1.
The PCI_DEVICE_ID_VMWARE_VMXNET3 macro is defined in mainline pci_ids.h
since commit b1226c7db1d9 ("vmxnet3: Move PCI Id to pci_ids.h") in
v4.10-rc1.
The MSR_MISC_FEATURES_ENABLES_CPUID_FAULT macro is defined in mainline
since commit e9ea1e7f53b8 ("x86/arch_prctl: Add ARCH_[GET|SET]_CPUID") in
v4.12-rc1.
The CR3_PCID_MASK is defined in mainline asm/processor-flags.h since commit
6c690ee1039b ("x86/mm: Split read_cr3() into read_cr3_pa() and
__read_cr3()") in v4.13-rc1.
As discussed in https://bugzilla.suse.com/show_bug.cgi?id=1059674 the reason for multiple objtool warnings is the fact that vmmon module defines its own Panic() function which never returns. While it is marked as such which is used by the compiler for optimization, there is no way to find this from object file. While this seems innocuous, it might result in problems with unwinder later. The quickest way around is to replace vmmon's own Panic() with standard kernel panic() until a cleaner solution is found.
Remove .cache.mk inside vmmon-only and vmnet-only when executing
"make clean". This file can cause issues when upgrading gcc as make will
still look for includes inside older gcc includes directory.
File .cache.mk with cache of generated variables was created by build since
kernel v4.15-rc1, commit 3298b690b21c ("kbuild: Add a cache for generated
variables") until the feature was removed in v4.18-rc1, commit e08d6de4e532
("kbuild: remove kbuild cache").
After mainline commit 13c01139b171 ("x86/headers: Remove APIC headers from
<asm/smp.h>") in 5.9-rc1, APIC headers are no longer included via
<asm/smp.h> so that linux/hostif.c will use incorrect fallback definitions
of SPURIOUS_APIC_VECTOR, POSTED_INTR_VECTOR and ERROR_APIC_VECTOR even if
built against kernel where these are defined.
Include <asm/irq_vectors.h> in linux/hostif.c explicitly to avoid that.
The do_gettimeofday() helper was removed by commit e4b92b108c6c
("timekeeping: remove obsolete time accessors") in v5.0-rc1 and since
commit c766d1472c70 ("y2038: hide timeval/timespec/itimerval/itimerspec
types") in v5.6-rc3, struct timeval should no longer be used in kernel
code.
Convert the do_gettimeofday() relics in VNetBridge (which are only compiled
with LOGLEVEL >= 4) completely to ktime based interface.
SLE15-SP5 backported mainline commit adeef3e32146 ("net: constify
netdev->dev_addr") from 5.17-rc1 into their "5.14" kernel. Add an extra
hack to the version check to fix SLE15-SP5 build.
While vmmon module already uses explicit module_init() and module_exit() for its init and cleanup function, vmnet relies on traditional magic names init_module() and cleanup_module(). Apparently this has an unfortunate side effect that the two functions are not identified as indirect call targets by objdump and they get "sealed" when the module is built against and loaded into an IBT enabled kernel. Starting with 6.3-rc1, objtool is going to warn about this issue, indicating that the legacy module initialization is deprecated and module_init() and module_exit() macros should be used instead so do that for vmnet as well.
Some cross page functions need an explicit endbr64 instruction as they are indirect branch targets but are not recognized as such. VMware 17 uses home cooked ENDBR macro rather than standard ASM_ENDBR defined in kernel. Use ASM_ENDBR instead and define it as empty if not available (kernel before 5.18-rc1) so that we do not generate useless endbr64 instructions when building against kernel which does not support IBT or has it disabled.
Mainline commit 6308499b5e99 ("net: unexport csum_and_copy_{from,to}_user")
in 5.19-rc1 unexports csum_and_copy_to_user as no in-tree module is using
it. A clean solution would probably be rewriting the code to use iovec
iterator as csum_and_copy_to_iter() is still exported (or perhaps
skb_copy_and_csum_datagram() might be used instead). Anything like this
would be way too intrusive so it would have to wait for VMware developers.
Workstation 17.0.0 handles this with a call to csum_partial_copy_nocheck()
inside a user_access_begin()/user_access_end() block which lets the build
succeed but objtool still warns about a call to csum_partial_copy_nocheck()
with UACCESS enabled. Based on the reasoning in commit message of mainline
commit ea24213d8088 ("objtool: Add UACCESS validation"), this workaround
does indeed seem questionable.
Use the older workaround combining csum_partial() with copy_to_user() like
in workstation-16.2.4 branch instead. This will be less efficient but
hopefully the performace hit will not be noticeable.
Mainline commit c304eddcecfe ("net: wrap the wireless pointers in struct
net_device in an ifdef") in 5.19-rc1 makess ieee80211_ptr member present in
struct net_device only if CONFIG_CFG80211 is enabled. Workstation 17.0.0
checks if CONFIG_CFG80211 is enabled but only when CONFIG_WIRELESS_EXT is
not. Thus a build against a kernel with CONFIG_WIRELESS_EXT enabled and
CONFIG_CFG80211 disabled still fails. Also, the newly introduced version
check is pointless, there is no point checking dev->ieee80211_ptr with
CONFIG_CFG80211 disabled (fortunately it will be null anyway).
Rewrite the check in VNetBridgeIsDeviceWireless() to check each of the two
pointers only if it actually exists.
Two functions use "foo()" rather than proper "foo(void)" in their definitions and as reported, clang compiler treats it as an error. While at it, also mark VNetFreeInterfaceList() static to make its definition match the declaration.
This also requires tweaking the Makefiles to allow for building for non-active kernels

Actual changes diff: workstation-17.5.1...philipl:vmware-host-modules:workstation-17.6.1 There is also https://github.com/bytium/vm-host-modules/tree/17.6.1 @philipl, by any chance do you know how to deal with #115 uninstalling? |

I use dkms (for which I include the dkms.conf file in my branch) which provides automatic build install and uninstall support. It's what I'd recommend everyone use. |

The only differences in 17.6.1 are changes that obsolete a few of the community patches. This works fine with 6.11.x.
