WMware developers decided to hack +around this by replacing pte_offset_map() by pte_offset_kernel() which does +not seem to be a good idea and apparently may trigger warn checks in RCU +code on some systems as mentioned in the discussion on issue #223. +Therefore let's use the same solution as we had for 17.0.2 and older +versions as it does not show these problems. + +Based on an upstream IRC discussion and the hva_to_pfn_*() family of +functions in KVM code, what PgtblVa2MPNLocked() does seems to be an +incomplete and partial open coded logic of get_user_pages() and as it is +only used to get PFN from a virtual address, it can be easily implemented +using get_user_pages() family. + +Without knowledge what exactly are the PFNs used for in VMware, it is hard +to guess the right flags, these seem to work and have been tested by +multiple users over last few weeks. + +We could likely use get_user_pages() also on older kernels and it might be +actually cleaner and more reliable as existing open coded implementation +does not seem to handle some corner cases but without knowledge of VMware +internals, it will be safer to stick to existing code where possible. +--- + vmmon-only/include/pgtbl.h | 25 +++++++++++++++++++++++++ + 1 file changed, 25 insertions(+) + +diff --git a/vmmon-only/include/pgtbl.h b/vmmon-only/include/pgtbl.h +index 3f43c62..7eaa49a 100644 +--- a/vmmon-only/include/pgtbl.h ++++ b/vmmon-only/include/pgtbl.h +@@ -25,6 +25,7 @@ + #include "compat_pgtable.h" + #include "compat_spinlock.h" + #include "compat_page.h" ++#include "compat_version.h" + + + /* +@@ -45,6 +46,7 @@ + *----------------------------------------------------------------------------- + */ + ++#if COMPAT_LINUX_VERSION_CHECK_LT(6, 5, 0) // only used by PgtblVa2MPN() below + static INLINE MPN + PgtblVa2MPNLocked(struct mm_struct *mm, // IN: Mm structure of a process + VA addr) // IN: Address in the virtual address +@@ -110,6 +112,7 @@ PgtblVa2MPNLocked(struct mm_struct *mm, // IN: Mm structure of a process + } + return mpn; + } ++#endif + + + /* +@@ -129,6 +132,8 @@ PgtblVa2MPNLocked(struct mm_struct *mm, // IN: Mm structure of a process + *----------------------------------------------------------------------------- + */ + ++#if COMPAT_LINUX_VERSION_CHECK_LT(6, 5, 0) ++ + static INLINE MPN + PgtblVa2MPN(VA addr) // IN + { +@@ -143,4 +148,24 @@ PgtblVa2MPN(VA addr) // IN + return mpn; + } + ++#else /* COMPAT_LINUX_VERSION_CHECK_LT(6, 5, 0) */ ++ ++static INLINE MPN ++PgtblVa2MPN(VA addr) // IN ++{ ++ struct page *page; ++ int npages; ++ MPN mpn; ++ ++ npages = get_user_pages_unlocked(addr, 1, &page, FOLL_HWPOISON); ++ if (npages != 1) ++ return INVALID_MPN; ++ mpn = page_to_pfn(page); ++ put_page(page); ++ ++ return mpn; ++} ++ ++#endif /* COMPAT_LINUX_VERSION_CHECK_LT(6, 5, 0) */ ++ + #endif /* __PGTBL_H__ */ |
